The Riddle of Philosophy Part 4

This tendency was then transplanted also to European soil and so entered into the European spiritual life through such thinkers as the great Aristotelians, Averroes (1126 1198), Maimonides (1135 1204), and others.

In Averroes, we find the view that it is an error to a.s.sume that a special thought world exists in the personality of man. There is only one h.o.m.ogeneous thought world in the divine primordial being. As light can be reflected in many mirrors, so also one thought world is revealed in many human beings.

During human life on earth, to be sure, a further transformation of the thought world takes place, but this is, in reality, only a process in the spiritually h.o.m.ogeneous primordial ground. With man's death, the individual revelation through him simply comes to an end. His thought life now exists only in the one thought life.

This world conception allows the Greek thought experience to continue its effect, but does it in such a way that it is now anch.o.r.ed in the uniform divine world ground. It leaves us with the impression of being a manifestation of the fact that the developing human soul did not feel in itself the intrinsic energy of thought. It therefore projected this energy into an extra-human world power.

Chapter IV.

The World Conceptions of the Middle Ages

A foreshadowing of a new element produced by thought life itself emerges in St. Augustine (354 430). This element soon vanishes from the surface, however, to continue unnoticeably under the cover of religious conception, becoming distinctly discernible again only in the later Middle Ages. In St.

Augustine, the new element appears as if it were a reminiscence of Greek thought life. He looks into the external world and into himself, and comes to the conclusion: May everything else the world reveals contain nothing but uncertainty and deception, one thing cannot be doubted, that is, the certainty of the soul's experience itself. I do not owe this inner experience to a perception that could deceive me; I am in it myself; it is, for I am present when its being is attributed to it.

One can see a new element in these conceptions as against Greek thought life, in spite of the fact that they seem at first like a reminiscence of it. Greek thinking points toward the soul; in St. Augustine, we are directed toward the center of the life of the soul. The Greek thinkers contemplated the soul in its relation to the world; in St. Augustine's approach, something in the soul life confronts this soul life and regards it as a special, self-contained world. One can call the center of the soul life the "ego" of man. To the Greek thinkers, the relation of the soul to the world becomes problematic, to the thinkers of modern times, that of the "ego" to the soul. In St.

Augustine, we have only the first indication of this situation.

The ensuing philosophical currents are still too much occupied with the task of harmonizing world conception and religion to become distinctly aware of the new element that

has not entered into spiritual life. But the tendency to contemplate the riddles of the world in accordance with the demand of this new element lives more or less unconsciously in the souls of the time that now follows. In thinkers like Anselm of Canterbury (1033 1109) and Thomas Aquinas (1227 1274), this tendency still shows itself in such a way that they attribute to self-supportive thinking the ability to investigate the processes of the world to a certain degree, but they limit this ability. There is for them a higher spiritual reality to which thinking, left to its own resources, can never attain, but that must be revealed to it in a religious way. Man is, according to Thomas Aquinas, rooted with his soul life in the reality of the world, but this soul life cannot know this reality in its full extent through itself alone. Man could not know how his own being stands in the course of the world if the spirit being, to which his knowledge does not penetrate, did not deign to reveal to him what must remain concealed to a knowledge relying on its own power alone. Thomas Aquinas constructs his world picture on this presupposition. It has two parts, one of which consists of the truths that are yielded to man's. own thought experience about the natural course of things. This leads to a second part that contains what has come to the soul of man through the Bible and religious revelation. Something that the soul cannot reach by itself, if it is to feel itself in its full essence, must therefore penetrate into the soul.

Thomas Aquinas made himself thoroughly familiar with the world conception of Aristotle, who becomes, as it were, his master in the life of thought. In this respect, Aquinas is, to be sure, the most prominent, but nevertheless only one of the numerous personalities of the Middle Ages who erect their own thought structure entirely on that of Aristotle. For centuries, he is il maestro di color che sanno, the master of those who know, as Dante expresses the veneration for

Aristotle in the Middle Ages. Thomas Aquinas strives to comprehend what is humanly comprehensible in Aristotelian method. In this way, Aristotle's world conception becomes the guide to the limit to which the soul life can advance through its own power for him. Beyond these boundaries lies the realm that the Greek world conception, according to Thomas, could not reach.

Therefore, human thinking for Thomas Aquinas is in need of another light by which it must be illuminated. He finds this light in revelation. Whatever was to be the att.i.tude of the ensuing thinkers with respect to this revelation, they could no longer accept the life of thought in the manner of the Greeks.

It is not sufficient to them that thinking comprehends the world; they make the presupposition that it should be possible to find a basic support for thinking itself. The tendency arises to fathom man's relation to his soul life. Thus, man considers himself a being who exists in his soul life. If one calls this ent.i.ty the ego, one can say that in modern times the consciousness of the ego is stirred up in man's soul life in a way similar to that in which thought was born in the philosophical life of the Greeks. Whatever different forms the philosophical currents in this age a.s.sume, they all hinge on the search for the ego-ent.i.ty. This fact, however, is not always brought clearly to the consciousness of the thinkers themselves. They mostly believe they are concerned with questions of a different nature. One could say that the Riddle of the Ego appears in a great variety of masks. At times it lives in the philosophy of the thinkers in such a concealed way that the statement that this riddle is at the bottom of some view or other might appear as an arbitrary or forced opinion. In the nineteenth century this struggle over the riddle of the ego comes to its most intensive manifestation, and the world conceptions of the present time are still profoundly engaged in this struggle.

This world riddle already lived in the conflict between the nominalists and the realists in the Middle Ages. One can call Anselm of Canterbury a representative of realism. For him, the general ideas that man forms when he contemplates the world are not mere nomenclatures that the soul produces for itself, but they have their roots in a real life. If one forms the general idea "lion" in order to designate all lions with it, it is certainly correct to say that, for sense perception, only the individual lions have reality. The general concept "lion" is not, however, only a summary designation with significance only for the human mind. It is rooted in a spiritual world, and the individual lions of the world of sense perception are the various embodiments of the one lion nature expressed in the "idea of lion."

Such a "reality of ideas" was opposed by Nominalists like Roscellin (also in the eleventh century). The "general ideas"

are only summary designations for him, names that the mind forms for its own use for its orientation, but that do not correspond to any reality. According to this view, only the individual things are real. The quarrel is characteristic of the specific mentality of its partic.i.p.ants. Both sides feel the necessity to search for the validity, the significance of the thoughts that the soul must produce. Their att.i.tude to thoughts as such is different from what the att.i.tudes of Plato and Aristotle were toward them. This is so because something has happened between the end of the development of Greek philosophy and the beginning of modern thought. Something has gone on under the surface of historical evolution that can, however, be observed in the att.i.tude that the individual thinkers take with respect to their thought life.

To the Greek thinker, thought came as a perception. It arose in the soul as the red color appears when a man looks at a rose, and the thinker received it as a perception. As such the thought had the immediate power of conviction. The Greek

thinker had the feeling, when he placed himself with his soul receptively before the spiritual world, that no incorrect thought could enter from this world into the soul just as no perception of a winged horse could come from the sense world as long as the sense organs were properly used. For the Greeks, it was a question of being able to garner thoughts from the world. They were then themselves the witnesses of their truth. The fact of this att.i.tude is not contradicted by the Sophists, nor is it denied by ancient Scepticism. Both currents have an entirely different shade of meaning in antiquity from similar tendencies in modern times. They are not evidence against the fact that the Greek experienced thought in a much more elementary, content-saturated, vivid and real way than it can be experienced by the man of modern times. This vividness, which in ancient Greece gave the character of perception to thought, is no longer to be found in the Middle Ages.

What has happened is this. As in Greek times thought entered into the human soul, extinguishing the formerly prevalent picture consciousness, so, in a similar way, during the Middle Ages the consciousness of the "ego" penetrated the human soul, and this dampened the vividness of thought. The advent of the ego-consciousness deprived thought of the strength through which it had appeared as perception. We can only understand how the philosophical life advances when we realize how, for Plato and Aristotle, the thought, the idea, was something entirely different from what it was for the personalities of the Middle Ages and modern times. The thinker of antiquity had the feeling that thought was given to him; the thinker of the later time had the impression that he was producing thought. Thus, the question arises in him as to what significance what has been produced in the soul can have for reality. The Greek felt himself to be a soul separated from the world; he attempted to unite with the spiritual world in

thought. The later thinker feels himself to be alone with his thought life. Thus, the inquiry into the nature of the "general ideas" begins. The thinker asks himself the questions, "What is it that I have really produced with them? Are they only rooted in me, or do they point toward a reality?"

In the period between the ancient current of philosophical life and that of modern philosophy, the source of Greek thought life is gradually exhausted. Under the surface, however, the human soul experiences the approaching ego-consciousness as a fact. Since the end of the first half of the Middle Ages, man is confronted with this process as an accomplished fact, and under the influence of this confrontation, new Riddles of Life emerge. Realism and Nominalism are symptoms of the fact that man realizes the situation. The manner in which both Realists and Nominalists speak about thought shows that, compared to its existence in the Greek soul, it has faded out, has been dampened as much as had been the old picture consciousness in the soul of the Greek thinker.

This points to the dominating element that lives in the modern world conceptions. An energy is active in them that strives beyond thought toward a new factor of reality. This tendency of modern times cannot be felt as the same that drove beyond thought in ancient times in Pythagoras and later in Plotinus. These thinkers also strove beyond thought but, according to their conception, the soul in its development, its perfection, would have to conquer the region that lies beyond thought. In modern times it is presupposed that the factor of reality lying beyond thought must approach the soul, must be given to it from without.

In the centuries that follow the age of Nominalism and Realism, philosophical evolution turns into a search for the new reality factor. One path among those discernible to the student of this search is the one the medieval Mystics -

Meister Eckhardt (died 1327), Johannes Tauler (died 1361), Heinrich Suso (died 1366) have chosen for themselves. We receive the clearest idea of this path if we inspect the so-called German Theology (Theologia, deutsch), written by an author historically unknown. The Mystics want to receive something into the ego-consciousness; they intend to fill it with something. They therefore strive for an inner life that is "completely composed," surrendered in tranquillity, and that thus patiently waits to experience the soul to be filled with the "Divine Ego." In a later time, a similar soul mood with a greater spiritual momentum can be observed in Angelus Silesius (1624 1677).

A different path is chosen by Nicolaus Cusa.n.u.s (Nicolaus Chrypffs, born at Kues on the Moselle, 1401, died 1464). He strives beyond intellectually attainable knowledge to a state of soul in which knowledge ceases and in which the soul meets its G.o.d in "knowing ignorance," in docta ignorantia.

Examined superficially, this aspiration is similar to that of Plotinus, but the soul const.i.tution of these two personalities is different. Plotinus is convinced that the human soul contains more than the world of thoughts. When it develops the energy that it possesses beyond the power of thought, the soul becomes conscious of the state in which it exists, and about which it is ignorant in ordinary life.

Paracelsus (1493 1541) already has the feeling with respect to nature, which becomes more and more p.r.o.nounced in the modern world conception, that is an effect of the soul's feeling of desolation in its ego-consciousness. He turns his attention toward the processes of nature. As they present themselves they cannot be accepted by the soul, but neither can thought, which in Aristotle unfolded in peaceful communication with the events of nature, now be accepted as it appears in the soul.

It is not perceived; it is formed in the soul. Paracelsus felt that one must not let thought itself speak; one must presuppose

that something is behind the phenomena of nature that will reveal itself if one finds the right relationship to these phenomena. One must be capable of receiving something from nature that one does not create oneself as thought during the act of observation. One must be connected with one's "ego" by means of a factor of reality other than thought.

A higher nature behind nature is what Paracelsus is looking for. His mood of soul is so const.i.tuted that he does not want to experience something in himself alone, but he means to penetrate nature's processes with his "ego" in order to have revealed to him the spirit of these processes that are under the surface of the world of the senses. The mystics of antiquity meant to delve into the depths of the soul; Paracelsus set out to take steps that would lead to a contact with the roots of nature in the external world.

Jakob Boehme (1575 1624) who, as a lonely, persecuted craftsman, formed a world picture as though out of an inner illumination, nevertheless implants into this world picture the fundamental character of modern times. In the solitude of his soul life he develops this fundamental trait most impressively because the inner dualism of the life of the soul, the contrast between the "ego" and the other soul experiences, stands clearly before the eye of his spirit. He experiences the "ego" as it creates an inner counterpart in its own soul life, reflecting itself in the mirror of his own soul. He then finds this inner experience again in the processes of the world. "In such a contemplation one finds two qualities, a good and an evil one, which are intertwined in this world in all forces, in stars and in elements as well as in all creatures." The evil in the world is opposed to the good as its counterpart; it is only in the evil that the good becomes aware of itself, as the "ego" becomes aware of itself in its inner soul experiences.

Chapter V.

The World Conceptions of the Modern Age of Thought Evolution

The rise of natural science in modern times had as its fundamental cause the same search as the mysticism of Jakob Boehme. This becomes apparent in a thinker who grew directly out of the spiritual movement, which in Copernicus (1473 1543), Kepler (1571 1630), Galileo (1564 1642), and others, led to the first great accomplishments of natural science in modern times. This thinker is Giordano Bruno (1548 1600). When one sees how his world consists of infinitely small, animated, psychically self-aware, fundamental beings, the monads, which are uncreated and indestructible, producing in their combined activity the phenomena of nature, one could be tempted to group him with Anaxagoras, for whom the world consists of the "h.o.m.oiomeries."

Yet, there is a significant difference between these two thinkers. For Anaxagoras, the thought of the h.o.m.oiomeries unfolds while he is engaged in the contemplation of the world; the world suggests these thoughts to him. Giordano Bruno feels that what lies behind the phenomena of nature must be thought of as a world picture in such a way that the ent.i.ty of the ego is possible in this world picture. The ego must be a monad; otherwise, it could not be real. Thus, the a.s.sumption of the monads becomes necessary. As only the monad can be real, therefore, the truly real ent.i.ties are monads with different inner qualities.

In the depths of the soul of a personality like Giordano Bruno, something happens that is not raised into full consciousness;

the effect of this inner process is then the formation of the world picture. What goes on in the depths is an unconscious soul process. The ego feels that it must form such a conception of itself that its reality is a.s.sured, and it must conceive the world in such a way that the ego can be real in it. Giordano Bruno has to form the conception of the monad in order to render possible the realization of both demands. In his thought the ego struggles for its existence in the world conception of the modern age, and the expression of this struggle is the view: I am a monad; such an ent.i.ty is uncreated and indestructible.

A comparison shows how different the ways are in which Aristotle and Giordano Bruno arrive at the conception of G.o.d.

Aristotle contemplates the world; he sees the evidence of reason in natural processes; he surrenders to the contemplation of this evidence; at the same time, the processes of nature are for him evidence of the thought of the "first mover" of these processes. Giordano Bruno fights his way through to the conception of the monads. The processes of nature are, as it were, extinguished in the picture in which innumerable monads are presented as acting on each other; G.o.d becomes the power ent.i.ty that lives actively in all monads behind the processes of the perceptible world. In Giordano Bruno's pa.s.sionate antagonism against Aristotle, the contrast between the thinker of ancient Greece and of the philosopher of modern times becomes manifest.

It becomes apparent in the modern philosophical development in a great variety of ways how the ego searches for means to experience its own reality in itself. What Francis Bacon of Verulam (1561 1626) represents in his writings has the same general character even if this does not at first sight become apparent in his endeavors in the field of philosophy.

Bacon of Verulam demands that the investigation of world phenomena should begin with unbiased observation. One

should then try to separate the essential from the nonessential in a phenomenon in order to arrive at a conception of whatever lies at the bottom of a thing or event. He is of the opinion that up to his time the fundamental thoughts, which were to explain the world phenomena, had been conceived first, and only thereafter were the description of the individual things and events arranged to fit these thoughts. He presupposed that the thoughts had not been taken out of the things themselves. Bacon wanted to combat this (deductive) method with his (inductive) method. The concepts are to be formed in direct contact with the things. One sees, so Bacon reasons, how an object is consumed by fire; one observes how a second object behaves with relation to fire and then observes the same process with many objects. In this fashion one arrives eventually at a conception of how things behave with respect to fire. The fact that the investigation in former times had not proceeded in this way had, according to Bacon's opinion, caused human conception to be dominated by so many idols instead of the true ideas about the things.

Goethe gives a significant description of this method of thought of Bacon of Verulam.

Bacon is like a man who is well-aware of the irregularity, insufficiency and dilapidated condition of an old building, and knows how to make this clear to the inhabitants. He advises them to abandon it, to give up the land, the materials and all appurtenances, to look for another plot, and to erect a new building. He is an excellent and persuasive speaker. He shakes a few walls. They break down and some of the inhabitants are forced to move out. He points out new building grounds; people begin to level it off, and yet it is everywhere too narrow. He submits new plans; they are not clear, not inviting.

Mainly, he speaks of new unknown materials and now the world seems to be well-served. The crowd disperses in all directions and brings back an infinite variety of single items

while at home, new plans, new activities and settlements occupy the citizens and absorb their attention.

Goethe says this in his history of the theory of color where he speaks about Bacon. In a later part of the book dealing with Galileo, he says: If through Verulam's method of dispersion, natural science seemed to be forever broken up into fragments, it was soon brought to unity again by Galileo. He led natural philosophy back into the human being. When he developed the law of the pendulum and of falling bodies from the observation of swinging church lamps, he showed even in his early youth that, for the genius, one case stands for a thousand cases. In science, everything depends on what is called, an apercu, that is, on the ability of becoming aware of what is really fundamental in the world of phenomena. The development of such an awareness is infinitely fruitful.

With these words Goethe indicated distinctly the point that is characteristic of Bacon. Bacon wants to find a secure path for science because he hopes that in this way man will find a dependable relationship to the world. The approach of Aristotle, so Bacon feels, can no longer be used in the modern age. He does not know that in different ages different energies of the soul are predominantly active in man. He is only aware of the fact that he must reject Aristotle. This he does pa.s.sionately. He does it in such a way that Goethe is lead to say, "How can one listen to him with equanimity when he compares the works of Aristotle and of Plato with weightless tablets, which, just because they did not consist of a good solid substance, could so easily float down to us on the stream of time."

Bacon does not understand that he is aiming at the same objective that has been reached by Plato and Aristotle, and

that he must use different means for the same aim because the means of antiquity can no longer be those of the modern age.

He points toward a method that could appear fruitful for the investigation in the field of external nature, but as Goethe shows in the case of Galileo, even in this field something more is necessary than what Bacon demands.

The method of Bacon proves completely useless, however, when the soul searches not only for an access to the investigation of individual facts, but also to a world conception. What good is a groping search for isolated phenomena and a derivation of general ideas from them, if these general ideas do not, like strokes of lightning, flash up out of the ground of being in the soul of man, rendering account of their truth through themselves. In antiquity, thought appeared like a perception to the soul. This mode of appearance has been dampened through the brightness of the new ego-consciousness. What can lead to thoughts capable of forming a world conception in the soul must be so formed as if it were the soul's own invention, and the soul must search for the possibility of justifying the validity of its own creation.

Bacon has no feeling for all this. He, therefore, points to the materials of the building for the construction of the new world conception, namely, the individual natural phenomena. It is, however, no more possible that one can ever build a house by merely observing the form of the building stones that are to be used, than that a fruitful world conception could ever arise in a soul that is exclusively concerned with the individual processes of nature.

Contrary to Bacon of Verulam, who pointed toward the bricks of the building, Descartes (Cartesius) and Spinoza turned their attention toward its plan. Descartes was born in 1596 and died in 1650. The starting point of his philosophical endeavor is significant with him. With an unbiased questioning mind he approaches the world, which offers him

much of its riddles partly through revealed religion, partly through the observation of the senses. He now contemplates both sources in such a way that he does not simply accept and recognize as truth what either of them offers to him. Instead, he sets against the suggestions of both sources the "ego,"

which answers out of its own initiative with its doubt against all revelation and against all perception. In the development of modern philosophical life, this move is a fact of the most telling significance. Amidst the world the thinker allows nothing to make an impression on his soul, but sets himself against everything with a doubt that can derive its support only from the soul itself. Now the soul apprehends itself in its own action: I doubt, that is to say, I think. Therefore, no matter how things stand with the entire world, in my doubt- exerting thinking I come to the clear awareness that I am. In this manner, Cartesius arrives at his Cogito ergo sum, I think, therefore I am. The ego in him conquers the right to recognize its own being through the radical doubt directed against the entire world.

Descartes derives the further development of his world conception out of this root. In the "ego" he had attempted to seize existence. Whatever can justify its existence together with the ego may be considered truth. The ego finds in itself, innate to it, the idea of G.o.d. This idea presents itself to the ego as true, as distinct as the ego itself, but it is so sublime, so powerful, that the ego cannot have it through its own power.

Therefore, it comes from transcendent reality to which it corresponds. Descartes believes in the reality of the external world, not because this external world presents itself as real, but because the ego must believe in itself and then subsequently in G.o.d, and because G.o.d must be thought as truthful. For it would be untrue of G.o.d to suggest a real external world to man if the latter did not exist.

It is only possible to arrive at the recognition of the reality of the ego as Descartes does through a thinking that in the most direct manner aims at the ego in order to find a point of support for the act of cognition. That is to say, this possibility can be fulfilled only through an inner activity but never through a perception from without. Any perception that comes from without gives only the qualities of extension. In this manner, Descartes arrives at the recognition of two substances in the world: One to which extension, and the other to which thinking, is to be attributed and that has its roots in the human soul. The animals, which in Descartes's sense cannot apprehend themselves in inner self-supporting activity, are accordingly mere beings of extension, automata, machines. The human body, too, is nothing but a machine.

The soul is linked up with this machine. When the body becomes useless through being worn out or destroyed in some way, the soul abandons it to continue to live in its own element.

Descartes lives in a time in which a new impulse in the philosophical life is already discernible. The period from the beginning of the Christian era until about the time of Scotus Erigena develops in such a way that the inner experience of thought is enlivened by a force that enters the spiritual evolution as a powerful impulse. The energy of thought as it awakened in Greece is outshone by this power. Outwardly, the progress in the life of the human soul is expressed in the religious movements and by the fact that the forces of the youthful nations of Western and Central Europe become the recipients of the effects of the older forms of thought experience. They penetrate this experience with the younger, more elementary impulses and thereby transform it. In this process one forward step in the progress in human evolution becomes evident that is caused by the fact that older and subtle traces of spiritual currents that have exhausted their

vitality, but not their spiritual possibilities, are continued by youthful energies emerging from the natural spring of mankind. In such processes one will be justified in recognizing the essential laws of the evolution of mankind.

They are based on rejuvenating tendencies of the spiritual life.

The acquired forces of the spirit can only then continue to unfold if they are transplanted into young, natural energies of mankind.

The first eight centuries of the Christian era present a continuation of the thought experience in the human soul in such a way that the new forces about to emerge are still dormant in hidden depths, but they tend to exert their formative effect on the evolution of world conception. In Descartes, these forces already show themselves at work in a high degree. In the age between Scotus Erigena and approximately the fifteenth century, thought, which in the preceding period did not openly unfold, comes again to the fore in its own force. Now, however, it emerges from a direction quite different from that of the Greek age. With the Greek thinkers, thought is experienced as a perception. From the eighth to the fifteenth centuries it comes from out of the depth of the soul so that man has the feeling: Thought generates itself within me. In the Greek thinkers, a relation between thought and the processes of nature was still immediately established; in the age just referred to, thought stands out as the product of self-consciousness. The thinker has the feeling that he must prove thought as justified. This is the feeling of the nominalists and the realists. This is also the feeling of Thomas Aquinas, who anchors the experience of thought in religious revelation.

The fifteenth and sixteenth centuries introduce a new impulse to the souls. This is slowly prepared and slowly absorbed in the life of the soul. A transformation takes place in the organization of the human soul. In the field of philosophical

life, this transformation becomes manifest through the fact that thought cannot now be felt as a perception, but as a product of self-consciousness. This transformation in the organization of the human soul can be observed in all fields of the development of humanity. It becomes apparent in the renaissance of art and science, and of European life, as well as in the reformatory religious movements. One will be able to discover it if one investigates the art of Dante and Shakespeare with respect to their foundations in the human soul development. Here these possibilities can only be indicated, since this sketch is intended to deal only with the development of the intellectual world conception.

The advent of the mode of thought of modern natural science appears as another symptom of this transformation of the human soul organization. Just compare the state of the form of thinking about nature as it develops in Copernicus, Galileo and Kepler with what has preceded them, This natural scientific conception corresponds to the mood of the human soul at the beginning of the modern age in the sixteenth century. Nature is now looked at in such a way that the sense observation is to be the only witness of it. Bacon is one, Galileo another personality in whom this becomes apparent.

The picture of nature is no longer drawn in a manner that allows thought to be felt in it as a power revealed by nature.

Out of this picture of nature, every trait that could be felt as only a product of self-consciousness gradually vanishes. Thus, the creations of self-consciousness and the observation of nature are more and more abruptly contrasted, separated by a gulf, From Descartes on a transformation of the soul organization becomes discernible that tends to separate the picture of nature from the creations of the self-consciousness.

With the sixteenth century a new tendency in the philosophical life begins to make itself felt. While in the preceding centuries thought had played the part of an

element, which, as a product of self-consciousness, demanded its justification through the world picture, since the sixteenth century it proves to be clearly and distinctly resting solely on its own ground in the self-consciousness. Previously, thought had been felt in such a manner that the picture of nature could be considered a support for its justification; now it becomes the task of this element of thought to uphold the claim of its validity through its own strength. The thinkers of the time that now follows feel that in the thought experience itself something must be found that proves this experience to be the justified creator of a world conception.
