The Riddle of Philosophy Part 19

Henry Mansel was a pupil and follower of Hamilton, but he expressed Hamilton's view in still more extreme forms. It is not going too far to say that Mansel was an advocate of belief who no longer judged impartially between religion and knowledge, but who defended religious dogma with partiality.

He was of the opinion that the revealed truths of religion involve our knowledge necessarily in contradictions. This is not supposed to be the fault of the revealed truths but has its cause in the limitation of the human mind, which can never penetrate into regions from which the statements of revelation arise.

William Whewell believed that he could best obtain a conception concerning the significance, origin and value of human knowledge by investigating the method through which leading men of science arrived at their insights. In his History of the Inductive Sciences (1840), he set out to a.n.a.lyze the psychology of scientific investigation. Thus, by studying outstanding scientific discoveries, he hoped to find out how much of these accomplishments was due to the external world and how much to man himself. Whewell finds that the human mind always supplements its scientific observations. Kepler, for example, had the idea of an ellipse before he found that the planets move in ellipses. Thus, the sciences do not come about through a mere reception from without but through the active partic.i.p.ation of the human mind that impresses its laws on the given elements. These sciences do not extend as far as the last ent.i.ties of things. They are concerned with the particulars of the world. Just as everything, for instance, is a.s.sumed to have a cause, such a cause must also be presupposed for the whole world. Since knowledge fails us with respect to that cause, the dogma of religion must step in as a supplement.

Herschel, like Whewell, also tried to gain an insight into the genesis of knowledge in the human mind through the observation of many examples. His Preliminary Discourse on

the Study of Natural Philosophy appeared in 1831.

John Stuart Mill belongs with those thinkers who are deeply imbued with the conviction that one cannot be cautious enough in determining what is certain and uncertain in human knowledge. The fact that he was introduced to the most diversified branches of knowledge in his boyhood, most likely gave his mind its characteristic turn. As a child of three he received instructions in the Greek language, and soon afterwards was taught arithmetic. He was exposed to the other fields of instruction at a correspondingly early age. Of even greater importance was the method of instruction used by his father, James Mill, who was himself an important thinker.

Through him vigorous logic became the second nature of John Stuart. From his autobiography we learn: "Anything which could be found out by thinking I was never told until I had exhausted my efforts to find it out for myself." The things that occupy the thinking of such a person must become his destiny in the proper sense of the word. "I have never been a child, I have never played cricket. It is, after all, better to let nature take its own course," says John Stuart Mill as one whose destiny had so uniquely been to live almost exclusively in thinking. Because of his development, he had to experience to the fullest the problems concerning the significance of knowledge. How can knowledge, which for him was life, lead also to the source of the phenomena of the world? The direction in which Mill's thought developed in order to obtain clarity concerning these problems was probably determined early by his father. James Mill had proceeded by starting from psychological experience. He had observed the process by which idea is linked to idea in man's mind. Through connecting one concrete idea to another we obtain our knowledge of the world. We must then ask ourselves: What is the relation between the order in which the ideas are linked and the order of the things in the world? Through such a

mode of conception our thinking begins to distrust its own power because man can a.s.sociate ideas in a manner that is entirely different from the connection of the things in the external world. This mistrust is the basis of John Stuart Mill's logic, which appeared in 1843 as his chief work under the t.i.tle, System of Logic.

In matters of world conception a more p.r.o.nounced contrast is scarcely thinkable than that between Mill's Logic and Hegel's Science of Logic, which appeared twenty-seven years earlier.

In Hegel we find the highest confidence in thinking, the full a.s.surance that we cannot be deceived by what we experience within ourselves. Hegel experiences himself as a part, a member of the world, and what he experiences within himself must also belong to the world. Since he has the most direct knowledge of himself, he believes in the content of this knowledge and judges the rest of the world accordingly. He argues as follows: When I perceive an external thing, it is possible that the thing shows only its surface to me and that its essence remains concealed. This is not possible in my own case. I understand my own being. I can then compare the things outside with my own being. If they reveal some element of my own essence on their surface, I am justified in attributing to them something of my own nature. It is for this reason that Hegel expects confidently to find outside in nature the very spirit and the thought connections that he finds within himself.

Mill, however, experiences himself not as a part of the world but as a spectator. The things outside are an unknown element to him and the thoughts that man forms concerning them are met by Mill with distrust. One observes men and learns from his observations that all men die. One forms the judgment that all men are mortal. The Duke of Wellington is a man; therefore, the Duke of Wellington is mortal. This is the conclusion the observer comes to. What gives him the right to

do so? This is the question John Stuart Mill asks. If a single human being would prove to be immortal, the whole judgment would be upset. Are we justified in supposing that, because all men up to this time have died, they will continue to do so in the future? All knowledge is uncertain because we draw conclusions from observations we have made and transfer them to things we cannot know anything about, since we have not observed them directly. What would somebody who thinks like Hegel have to say about such a conception? It is not difficult to imagine the answer. We know from definite concepts that in every circle all diameters are equal. If we find a circle in the real world, we maintain that its diameters, too, are equal. If we observe it a quarter of an hour later and find that its diameters are unequal, we do not decide that under certain circ.u.mstances the diameter of a circle can also be unequal. But we say that what was formerly a circle has for some reason been elongated into an ellipse.

If we think like Hegel, this is the att.i.tude we take toward the judgment, all men are mortal. It is not through observation but through an inner thought experience that we form the concept of man. For the concept of man, mortality is as essential as the equality of the diameters is for the concept of the circle. If we find a being in the real world that has all the other characteristics of man, we conclude that this being must also have that of mortality, in the same way that all other properties of the circle allow us to conclude that it has also that of the equality of diameters. If Hegel came across a being that did not die, he could only say, "That is not a man." He could not say, "A man can also be immortal." Hegel makes the a.s.sumption that the concepts in us are not arbitrarily formed but have their root in the essence of the world, as we ourselves belong to this essence. Once the concept of man has formed within us, it is clear that it has its origin in the essence of things, and we are fully justified in applying it to this essence.

Why has this concept of mortal man formed within us? Surely only because it has its ground in the nature of things. A person who believes that man stands entirely outside of the order of things and forms his judgments as an outsider can argue that we have until now seen men die, and therefore we form the spectator concept: mortal men. The thinker who is aware that he himself belongs to the order of things and that it is they that are manifested within his thoughts, forms the judgment that up to this time all men have died; to die, then, is something that belongs to their nature, and if somebody does not die, he is not a man but something else. Hegel's logic has become a logic of things: For Hegel, the manifestation of logic is an effect of the essence of the world; it is not something that the human mind has added from an outside source to this essence. Mill's logic is the logic of a bystander, of a mere spectator who starts out by cutting the thread through which it is connected with the world.

Mill points out that the thoughts, which in a certain age appear as absolutely certain inner experiences, are nevertheless reversed in a later time. In the Middle Ages it was, for instance, believed that there could not possibly be antipodes and that the stars would have to drop from the sky if they did not cling to fixed spheres. Man will, therefore, only be capable of the right att.i.tude toward his knowledge if he, in spite of his awareness that the logic of the world is expressed in this knowledge, forms in every individual case his judgment through a careful methodical examination of his conceptual connections guided by observation, a judgment that is always in need of correction.

It is the method of observation that John Stuart Mill attempts to determine with cool detachment and calculation. Let us take an example. Suppose a phenomenon had always occurred under certain conditions. In a given case a number of these conditions appear again, but a few of them are now missing.

The phenomenon in question does not occur. We are forced to conclude that the conditions that were not provided and the phenomenon that failed to occur stood in a causal relations.h.i.+p. If two substances have always combined to form a chemical compound and this result fails to be obtained in a given case, it is necessary to inquire what condition is lacking that had always been present before. Through a method of this kind we arrive at conceptions concerning connections of facts that can be rightly considered as being grounded in the nature of things. Mill wants to follow the methods of observation in his a.n.a.lysis. Logic, which Kant maintained had not progressed a single step since Aristotle, is a means of orientation within our thinking itself. It shows how to proceed from one correct thought to the next. Mill's logic is a means of orientation within the world of facts. It intends to show how one obtains valid judgments about things from observation. He does not even admit mathematics as an exception. Mathematics must also derive its basic insights from observation. For example, in all observed cases we have seen that two intersecting straight lines diverge and do not intersect again. Therefore we conclude that they will never intersect again, but we do not have a perfect proof for this statement. For John Stuart Mill, the world is thus an alien element. Man observes its phenomena and arranges them according to what they announce to his conceptual life. He perceives regularities in the phenomena and through logical, methodical investigations of these regularities he arrives at the laws of nature. But there is nothing that leads him to the principle of the things themselves. One can well imagine that the world could also be entirely different. Mill is convinced that everybody who is used to abstraction and a.n.a.lysis and who seriously uses his abilities will, after a sufficient exercise of his imagination, have no difficulty with the idea that there could be another stellar system in which nothing could be found of the laws that have application to our own.

Mill is merely consistent in his bystander viewpoint of the world when he extends it to man's own ego. Mental pictures come and go, are combined and separated within his inner life; this is what man observes. He does not observe a being that remains identical with itself as "ego" in the midst of this constant flow of ideas. He has observed that mental pictures emerge within him and he a.s.sumes that this will continue to be the case. From this possibility, namely, that a world of perceptions can be grouped around a center, arises the conception of an "ego." Thus, man is a spectator also with respect to his own "ego." He has his conceptions tell him what he can know about himself. Mill reflects on the facts of memory and expectation. If everything that I know of myself is to consist of conceptual presentations, then I cannot say: I remember a conception that I have had at an earlier time, or I expect the occurrence of a certain experience, but I must say: A present conception remembers itself or expects its future occurrence. If we speak, so Mill argues, of the mind as of a sequence of perceptions, we must also speak of a sequence of perceptions that is aware of itself as becoming and pa.s.sing. As a result, we find ourselves in the dilemma of having to say that either the "ego" or the mind is something to be distinguished from the perceptions, or else we must maintain the paradox that a mere sequence of perceptions is capable of an awareness of its past and future. Mill does not overcome this dilemma. It contains for him an insoluble enigma. The fact is that he has torn the bond between himself, the observer, and the world, and he is not capable of restoring the connection.

The world for him remains an unknown beyond himself that produces impressions on man. All man knows of this transcendent unknown is that it can produce perceptions in him. Instead of having the possibility of knowing real things outside himself, he can only say in the end that there are opportunities for having perceptions. Whoever speaks of things in themselves uses empty words. We move on the firm

ground of facts only as long as we speak of the continuous possibility of the occurrence of sensations, perceptions and conceptions.

John Stuart Mill has an intense aversion to all thoughts that are gained in any way except through the comparison of facts, the observation of the similar, the a.n.a.logous, and the h.o.m.ogeneous elements in all phenomena. He is of the opinion that the human conduct of life can only be harmed if we surrender to the belief that we could arrive at any truth in any way except through observation. This disinclination of Mill demonstrates his hesitation to relate himself in his striving for knowledge to the things of reality in any other way than by an att.i.tude of pa.s.sivity. The things are to dictate to man what he has to think about them. If man goes beyond this state of receptivity in order to say something out of his own self about the things, then he lacks every a.s.surance that this product of his own activity has anything to do with the things. What is finally decisive in this philosophy is the fact that the thinker who maintains it is unable to count his own spontaneous thinking as belonging to the world. The very fact that he himself is active in this thinking makes him suspicious and misleads him. He would best of all like to eliminate his own self completely, to be absolutely sure that no erroneous element is mixed into the objective statements of the phenomena. He does not sufficiently appreciate the fact that his thinking is a part of nature as much as the growth of a leaf of gra.s.s. It is evident that one must also examine one's own spontaneous thinking if one wants to find out something concerning it.

How is man, to use a statement of Goethe, to become acquainted with his relation to himself and to the external world if he wants to eliminate himself completely in the cognitive process? Great as Mill's merits are for finding methods through which man can learn those things that do

not depend on him, a view concerning man's relation to himself and of his relation to the external world cannot be obtained by his methods. All these methods are valid only for the special sciences, not, however, for a comprehensive world conception. No observation can teach what spontaneous thinking is; only thinking can experience this in itself. As this thinking can only obtain information concerning its own nature through its own power, it is also the only source that can shed light on the relation between itself and the external world. Mill's method of investigation excludes the possibility of obtaining a world conception because a world conception can be gained only through thinking that is concentrated in itself and thereby succeeds in obtaining an insight into its own relation to the external world. The fact that John Stuart Mill had an aversion to this kind of self-supporting thinking can be well understood from his character.

Gladstone said in a letter (compare Gompertz: John Stuart Mill, Vienna, 1889) that in conversation he used to call Mill the "Saint of Rationalism." A person who practices thinking in this way imposes rigorous demands on thinking and looks for the greatest possible precautionary measures so that it cannot deceive him. He becomes thereby mistrustful with respect to thinking itself. He believes that he will soon stand on insecure ground if he loses hold of external points of support.

Uncertainty with regard to all problems that go beyond strictly observational knowledge is a basic trait in Mill's personality.

In reading his books we see everywhere that Mill treats such problems as open questions concerning which he does not risk a sure judgment.

The belief that the true nature of things is unknowable is also maintained by Herbert Spencer. He proceeds by asking: How do I obtain what I call truths concerning the world? I make

certain observations concerning things and form judgments about them. I observe that hydrogen and oxygen under certain conditions combine to form water. I form a judgment concerning this observation. This is a truth that extends only over a small circle of things. I then observe under what circ.u.mstances other substances combine. I compare the individual observations and thereby arrive at more comprehensive, more general truths concerning the process in which substances in general form chemical compounds. All knowledge consists in this; we proceed from particular truths to more comprehensive ones. We finally arrive at the highest truth, which cannot be subordinated to any other and which we therefore must accept without further explanation. In this process of knowledge we have, however, no means of penetrating to the absolute essence of the world, for thinking can, according to this opinion, do no more than compare the various things with one another and formulate general truths with respect to the h.o.m.ogeneous element in them. But the ultimate nature of the world cannot, because of its uniqueness, be compared to any other thing. This is why thinking fails with regard to the ultimate nature. It cannot reach it.

In such modes of conception we always sense, as an undertone, the thinking that developed from the basis of the physiology of the senses (compare above to the first part of this Chapter). In many philosophers this thought has inserted itself so deeply into their intellectual life that they consider it the most certain thought possible. They argue as follows: One can know things only by becoming aware of them. They then change this thought, more or less unconsciously, into: One can know only of those things that enter our consciousness, but it remains unknown how the things were before they entered our consciousness. It is for this reason that sense perceptions are considered as if they

were in our consciousness, for one is of the opinion that they must first enter our consciousness and must become part of it in the form of conceptions if we are to be aware of them.

Also, Spencer clings to the view that the possibility of the process of knowledge depends on us as human beings. We therefore must a.s.sume an unknowable element beyond that which can be transmitted to us by our senses and our thinking. We have a clear consciousness of everything that is present in our mind. But an indefinite consciousness is a.s.sociated with this clear awareness that claims that everything we can observe and think has as its basis something we can no longer observe and think. We know that we are dealing with mere appearances and not with full realities existing independently by themselves. But this is just because we know definitely that our world is only appearance, that we also know that an unimaginable real world is its basis.

Through such turns of thought Spencer believes it possible to arrange a complete reconciliation between religion and knowledge. There is something that religion can grasp in belief, in a belief that cannot be shaken by an impotent knowledge.

The field, however, that Spencer considers to be accessible to knowledge must, for him, entirely take on the form of natural scientific conceptions. When Spencer himself ventures to explain, he does so in the sense of natural science.

Spencer uses the method of natural science in thinking of the process of knowledge. Every organ of a living being has come into existence through the fact that this being has adapted itself to the conditions under which it lives. It belongs to the human conditions of life that man finds his way through the world with the aid of thinking. His organ of knowledge develops through the adaptation of his conceptual life to the conditions of his external life. By making statements

concerning things and processes, man adjusts himself to the surrounding world. All truths have come into being through this process of adaptation, and what is acquired in this way can be transmitted through inheritance to the descendants.

Those who think that man, through his nature, possesses once and for all a certain disposition toward general truths are wrong. What appears to be such a disposition did not exist at an earlier stage in the ancestors of man, but has been acquired by adaptation and transmitted to the descendants. When some philosophers speak of truths that man does not have to derive from his own individual experience but that are given a priori in his organization, they are right in a certain respect.

While it is obvious that such truths are acquired, it must be stressed that they are not acquired by man as an individual but as a species. The individual has inherited the finished product of an ability that has been acquired at an earlier age.

Goethe once said that he had taken part in many conversations on Kant's Critique of Pure Reason and that he had noticed how on those occasions the old basic problem had been renewed, "How much does our inner self contribute to our spiritual existence, how much the external world?" And Goethe goes on to say, "I had never separated the two; when I was philosophizing in my own way on things, I did so with an unconscious naivete and was really convinced that I saw with my eyes my opinion before me."

Spencer looks at this "old basic problem" from the point of view of natural science. He believed he could show that the developed human being also contributed to his spiritual existence through his own self. This self, is also made up of the inherited traits that had been acquired by our ancestors in their struggle with the external world. If we today believe we see with our eyes our opinions before us, we must remember that they were not always our opinions but that they were once observations that were really made by our eyes in the

external world. Spencer's way of thinking, then, is, like that of John Stuart Mill, one that proceeds from psychology. But Mill does not go further than the psychology of the individual.

Spencer goes from the individual back to his ancestors. The psychology of the individual is in the same position as the ontogenesis of zoology. Certain phenomena of the history of the individual are explainable only if they are referred back to phenomena of the history of the species. In the same way, the facts of the individual's consciousness cannot be understood if taken alone. We must go back to the species. We must, indeed, go back beyond the human species to acquisitions of knowledge that were accomplished by the animal ancestors of man. Spencer uses his great ac.u.men to support this evolutionary history of the process of cognition. He shows in which way the mental activities have gradually developed from low stages at the beginning, through ever more accurate adaptations of the human mind to the external world and through inheritance of these adaptation. Every insight that the individual human being obtains through pure thought and without experience about things has been obtained by humanity or its ancestors through observation or experience.

Leibniz thought he could explain the correspondence of man's inner life with the external world by a.s.suming a harmony between them that was preestablished by the creator. Spencer explains this correspondence in the manner of natural science. The harmony is not pre-established, but gradually developed. We here find the continuation of natural scientific thinking to the highest aspects of human existence. Linnaeus had declared that every living organic form existed because the creator had made it as it is. Darwin maintained that it is as it is because it had gradually developed through adaptation and inheritance. Leibniz declared that thinking is an agreement with the external world because the creator had established this agreement. Spencer maintained that this agreement is there because it has gradually developed through

adaptations and inheritance of the thought world.

Spencer was motivated in his thought by the need for a naturalistic explanation of spiritual phenomena. He found the general direction for such an explanation in Lyell's geology (compare in Part 2 Chapter I). In this geology, to be sure, the idea is still rejected that organic forms have gradually developed one from another. It nevertheless receives a powerful support through the fact that the inorganic (geological) formations of the earth's surface are explained through such a gradual development and through violent catastrophes. Spencer, who had a natural scientific education and who had for a time also been active as a civil engineer, recognized at once the full extent of the idea of evolution, and he applied it in spite of Lyell's opposition to it. He even applied this idea to spiritual processes. As early as 1850, in his book, Social Statistics, he described social evolution in a.n.a.logy with organic evolution. He also acquainted himself with the studies of Harvey and Wolff in embryonic development (compare Part I, Chapter IX of this book), and he plunged into the works of Karl Ernst von Baer (compare above in Part II Chapter II), which showed him that evolution proceeded from the development of a h.o.m.ogeneous uniform state to one of variety, diversity and abundance. In the early stages of embryological development the organisms are very similar; later they become different from one another (compare above in Part II Chapter II).

Through Darwin this evolutionary thought was completely confirmed. From a few original organic forms the whole wealth of the highly diversified world of formations has developed.

From the idea of evolution, Spencer wanted to proceed to the most general truths, which, in his opinion, const.i.tuted the aim of all human striving for knowledge. He believed that one could discover manifestations of this evolutionary thought in

the simplest phenomena. When, from dispersed particles of water, a cloud is formed in the sky, when a sand pile is formed from scattered grains of sand, Spencer saw the beginnings of an evolutionary process. Dispersed matter is contracted and concentrated to a whole. It is just this process that is presented to us in the Kant-Laplace hypothesis of world evolution. Dispersed parts of a chaotic world nebula have contracted. The organism originates in just this way.

Dispersed elements are concentrated in tissues. The psychologist can observe that man contracts dispersed observations into general truths. Within this concentrated whole, articulation and differentiation take place. The original h.o.m.ogeneous ma.s.s is differentiated into the individual heavenly bodies of the solar system; the organism differentiates itself into the various organs.

Concentration alternates with dissolution. When a process of evolution has reached a certain climax, an equilibrium takes place. Man, for instance, develops until he has evolved a maximum of harmonization of his inner abilities with external nature. Such a state of equilibrium, however, cannot last; external forces will effect it destructively. The evolutionary process must be followed by a process of dissolution; what had been concentrated is dispersed again; the cosmic again becomes chaotic. The process of evolution can begin anew.

Thus, Spencer sees the process of the world as a rhythmic play of motion. It is certainly not an uninteresting observation for the comparative history of the evolution of world conception that Spencer, from the observation of the genesis of world phenomena, reaches here a conclusion that is similar to one Goethe expressed in connection with his ideas concerning the genesis of life. Goethe describes the growth of a plant in the following way: May the plant sprout, blossom or bear fruit, it is always by the same organs that the prescription of nature is fulfilled in

various functions and under frequently changing forms. The same organ, which at the stem expands as a leaf and takes on a most differentiated shape, now contracts again in the calyx, spreads out in the petal, epitomizes in the organs of reproduction and finally once more swells as fruit.

If one thinks of this conception as being transferred to the whole process of the world, one arrives as Spencer's contraction and dispersion of matter.

Spencer and Mill exerted a great influence on the development of world conception in the second half of the nineteenth century. The rigorous emphasis on observation and the one-sided elaboration of the methods of observational knowledge of Mill, along with the application of the conceptions of natural science to the entire scope of human knowledge by Spencer could not fail to meet with the approval of an age that saw in the idealistic world conception of Fichte, Sch.e.l.ling and Hegel nothing but degeneration of human thinking. It was an age that showed appreciation only for the successes of the research work of natural science. The lack of unity among the idealistic thinkers and what seemed to many a perfect fruitfulness of a thinking that was completely concentrated and absorbed in itself, had to produce a deep- seated suspicion against idealism. One may say that a widespread view of the last four decades of the nineteenth century is clearly expressed in words spoken by Rudolf Virchow in his address, The Foundation of the University of Berlin and the Transition from the Age of Philosophy into that of Natural Science (1893): "Since the belief in magic formulas has been forced back into the most backward circles of the people, the formulas of the natural philosopher have met with little approval." And one of the most significant philosophers of the second half of the century, Eduard von

Hartmann, sums up the character of his world conception in the motto he placed at the head of his book, Philosophy of the Unconscious: Speculative Results Obtained by the Inductive Method of Natural Science. He is of the opinion that it is necessary to recognize "the greatness of the progress brought about by Mill, through which all attempts of a deductive method of philosophy have been defeated and made obsolete for all times." (Compare Eduard von Hartmann, Geschichte der Metaphysik, 2 part, page 479.) The recognition of certain limits of human knowledge that was shown by many naturalists was also received favorably by many religiously attuned souls. They argued as follows: The natural scientists observe the inorganic and organic facts of nature and they attempt to find general laws by combining the individual phenomena. Through these laws processes can be explained, and it is even possible to predetermine thereby the regular course of future phenomena. A comprehensive world conception should proceed in the same way; it should confine itself to the facts, establish general truths within moderate limits and not maintain any claim to penetrate into the realm of the "unknowable." Spencer, with his complete separation of the "knowable" and the "unknowable," met the demand of such religious needs to a high degree. The idealistic mode of thought was, on the other hand, considered by such religiously inclined spirits to be a fantastic aberration. As a matter of principle, the idealistic mode of conception cannot recognize an "unknowable," because it has to uphold the conviction that through the concentrated penetration into the inner life of man a knowledge can be attained that covers not merely the outer surface of the world but also its real core.

The thought life of some influential naturalists, such as Thomas Henry Huxley, moved entirely in the direction of such religiously inclined spirits. Huxley believed in a complete agnosticism with regard to the essence of the world. He

declared that a monism, which is in general agreement with Darwin's results, is applicable only to external nature. Huxley was one of the first to defend the Darwinian conceptions, but he is at the same time one of the most outspoken representatives of those thinkers who believed in the limitation of that mode of conception. A similar view is also held by the physicist Johaan Tyndall (1820 93) who considered the world process to be an energy that is completely inaccessible to the human intellect. According to him, it is precisely the a.s.sumption that everything in the world comes into existence through a natural evolution that makes it impossible to accept the thought that matter, which is, after all, the carrier of the whole evolution, should be no more than what our intellect can comprehend of it.

A characteristic phenomenon of his time is the personality of the English statesman, James Balfour (1840 1930). In 1879, in his book, A Defense of Philosophical Doubt, Being an Essay on the Foundations of Belief, he expressed a credo that is doubtless similar to that held by many other thinkers. With respect to everything that man is capable of explaining he stands completely on the ground of the thought of natural science. For him, there is no other knowledge but natural science, but he maintains at the same time that his knowledge of natural science is only rightly understood if it is clear that the needs of man's soul and reason can never be satisfied by it.

It is only necessary to understand that, in the last a.n.a.lysis even in natural science, everything depends on faith in the ultimate truths for which no further proof is possible. But no harm is done in that this trend of thoughts leads us only to belief, because this belief is a secure guide for our action in daily life. We believe in the laws of nature and we master them through this belief. We thereby force nature to serve us for our purpose. Religious belief is to produce an agreement between

the actions of man and his higher needs that go beyond his everyday life.

The world conceptions that have been discussed under the t.i.tle, "The World as Illusion," show that they have as their basis a longing for a satisfactory relations.h.i.+p of the self- conscious ego to the general world picture. It is especially significant that they do not consciously consider this search as their philosophical aim, and therefore do not expressly turn their inquiry toward that purpose. Instinctively as it were, they permit their thinking to be influenced by the direction that is determined by this unconscious search. The form that this search takes is determined by the conceptions of modern natural science. We approach the fundamental character of these conceptions if we fix our attention on the concept of "consciousness." This concept was introduced to the life of modern philosophy by Descartes. Before him, it was customary to depend more on the concept of the "soul" as such. Little attention was paid to the fact that only a part of the soul's life is spent in connection with conscious phenomena. During sleep the soul does not live consciously.

Compared to the conscious life, the nature of the soul must therefore consist of deeper forces, which in the waking state are merely lifted into consciousness. The more one asked the question of the justification and the value of knowledge in the light of clear and distinct ideas, however, the more it was also felt that the soul finds the most certain elements of knowledge when it does not go beyond its own limits and when it does not delve deeper into itself than consciousness extends. The opinion prevailed that everything else may be uncertain, but what my consciousness is, at least, as such is certain. Even the house I pa.s.s may not exist without me; that the image of this house is now in my consciousness: this I may maintain. But as soon as we fix our attention on this consciousness, the concept of the ego inevitably grows together with that of the

consciousness. Whatever kind of ent.i.ty the "ego" may be outside the consciousness, the realm of the "ego" can be conceived as extending as far as the consciousness. There is no possibility of denying that the sensual world picture, which the soul experiences consciously, has come into existence through the impression that is made on man by the world. But as soon as one clings to this statement, it becomes difficult to rid oneself of it, for there is a tendency thereby to imply the judgment that the processes of the world are the causes, and that the content of our consciousness is the effect. Because one thinks that only the effect is contained in the consciousness, it is believed that the cause must be in a world outside man as an imperceptible "thing in itself." The presentation that is given above shows how the results of modern physiological research lead to an affirmation of such an opinion. It is just this opinion through which the "ego"

finds itself enclosed with its subjective experiences within its own boundaries. This subtly produced intellectual illusion, once formed, cannot be destroyed as long as the ego does not find any clues within itself of which it knows that they refer to a being outside the subjective consciousness, although they are actually depicted within that consciousness. The ego must, outside the sensual consciousness, feel a contact with ent.i.ties that guarantee their being by and through themselves. It must find something within that leads it outside itself. been said here concerning thoughts that are brought to life can have this effect. As long as the ego has experienced thought only within itself, it feels itself confined with it within its own boundary.

As thought is brought to life it emanc.i.p.ates the ego from a mere subjective existence. A process takes place that is, to be sure, experienced subjectively by the ego, but by its own nature is an objective process. This breaks the "ego" loose from everything that it can feel only as subjective.

So we see that also the conceptions for which the world is illusion move toward a point that is reached when Hegel's world picture is so transformed that its thought comes to life.

These conceptions take on the form that is necessary for a world picture that is unconsciously driven by an impulse in that direction. But in them, thinking still lacks the power to work its way through to that aim. Even in their imperfection, however, these conceptions receive their general character from this aim, and the ideas that appear are the external symptoms of active forces that remain concealed.

Echoes of the Kantian Mode of Conception

Only a few personalities in the second half of the nineteenth century attempted to find a firm foundation for the relation of a conception of the self-conscious ego toward the general world picture by going deeply into Hegel's mode of thought.

One of the best thinkers along these lines was Paul Asmus (1842 1876), who died as a young man. In 1873 he published a book ent.i.tled, The Ego and the Thing in Itself. In it he shows how it is possible, through Hegel's approach to thinking and the world of ideas, to obtain a relation of man toward the essence of things. He explains in an ingenious way that we have in man's thinking an element that is not alien to reality but full of life and fundamentally real, an element on which we only have to concentrate in order to arrive at the essence of existence. In a most illuminating way he describes the course of the evolution of world conception that began with Kant, who had seen in the "thing in itself" an element that was alien and inaccessible to man, and led to Hegel, who was of the opinion that thought comprised not only itself as an ideal ent.i.ty but also the "thing in itself." Voices like this found scarcely a hearing. This became most poignantly clear in the slogan, "Back to Kant," which became popular in a certain current of philosophical life after Eduard Zeller's speech at the University of Heidelberg, On the Significance and Task of the Theory of Knowledge.
