5. THE ADVANCEMENT OF THE NATURAL SCIENCES.—To all these phenomena, which should be regarded both as causes and as symptoms of the intellectual revolution of this period, we must add yet another, which essentially facilitated and gave a positive assistance to the freedom of the mind from the fetters of authority—the starting up of the natural sciences and the inductive method of examining nature. This epoch was a period of the most fruitful and influential discoveries in nature. The discovery of America and the passage to the East Indies had already widened the circle of view, but still greater revolutions are connected with the name of a _Copernicus_ (died 1543), _Kepler_ (died 1630), and _Galileo_ (died 1642), revolutions which could not remain, without an influence upon the whole mode of thinking of that age, and which contributed prominently to break the faith in the prevailing ecclesiastical authority. Scholasticism had turned away from nature and the phenomenal world, and, blind towards that which lay before the very eyes, had spent itself in a dreamy intellectuality; but now nature rose again in honor; her glory and exaltation, her infinite diversity and fulness of life became again the immediate objects of observation; to investigate nature became an essential object of philosophy, and scientific empiricism was thus regarded as a universal and essential concern of the thinking man. From this time the natural sciences date their historical importance, for only from this time have they had an uninterrupted history. The results of this new intellectual movement can be readily estimated. Such a scientific investigation of nature not only destroyed a series of traditional errors and prejudices, but, what was of greater importance, it directed the intellectual interest towards that which is real and actual, it nourished and protected the self-thinking and feeling of self-dependence, the spirit of inquiry and proof. The standpoint of observation and experiment presupposes an independent self-consciousness of the individual, a breaking loose from authority—in a word, scepticism, with which, in fact, the founders of modern philosophy, _Bacon_ and _Descartes_, began; the former by conditioning the knowledge of nature upon the removal of all prejudice and every preconceived opinion, and the latter by demanding that philosophy should be begun with universal doubt. No wonder that a bitter struggle should soon break out between the natural sciences and ecclesiastical orthodoxy, which could only result in breaking the power of the latter.

6. BACON OF VERULAM.—Francis of Verulam was born in 1561, and was Lord High Chancellor of England and keeper of the king’s seal under James I. From these offices he was subsequently expelled, and died in 1626, with a character which has not been without reproach. He took as his principle the inductive method, which he directed expressly against Scholasticism and the ruling scientific method. On this account he is frequently placed at the head of modern philosophy.

The sciences, says Bacon, have hitherto been in a most sad condition. Philosophy, wasted in empty and fruitless logomachies, has failed during so many centuries to bring out a single work or experiment of actual benefit to human life. Logic hitherto has served more to the establishment of error than to the investigation of truth. Whence all this? Why this penury of the sciences? Simply because they have broken away from their root in nature and experience. The blame of this is chargeable to many sources; first, the old and rooted prejudice that the human mind loses somewhat of its dignity when it busies itself much and continuously with experiments and material things; next, superstition and a blind religious zeal, which has been the most irreconcilable opposer to natural philosophy; again, the exclusive attention paid to morals and politics by the Romans, and since the Christian era to theology by every acute mind; still farther, the great authority which certain philosophers have professed, and the great reverence given, to antiquity; and in fine, a want of courage and a despair of overcoming the many and great difficulties which lie in the way of the investigation of nature. All these causes have contributed to keep down the sciences. Hence they must now be renewed, and regenerated, and reformed in their most fundamental principles; there must now be found a new basis of knowledge and new principles of science. This radical reformation of the sciences depends upon two conditions, objectively upon the referring of science to experience and the philosophy of nature, and subjectively upon the purifying of the sense and the intellect from all abstract theories and traditional prejudices. Both conditions furnish the correct method of natural science, which is nothing other than the method of induction. Upon a true induction depends all the soundness of the sciences.

In these propositions the Baconian philosophy is contained. The historical significance of its founder is, therefore, in general this,—that he directed the attention and reflection of his contemporaries again upon the given actuality, upon nature; that he affirmed the necessity of experience, which had been formerly only a matter of accident, and made it as in and for itself an object of thought. His merit consists in having brought up the principle of scientific empiricism, and only in this. Strictly speaking, we can allow no _content_ to the Baconian philosophy, although (in his treatise _de augmentis scientiarum_) he has attempted a systematic encyclopedia of the sciences according to a new principle of classification, through which he has scattered an abundance of fine and fruitful observations, which are still used as apothegms.

7. THE ITALIAN PHILOSOPHERS OF THE TRANSITION EPOCH.—Besides Bacon, other phenomena must be noticed which have prepared and introduced the new age of philosophy. First among these is a list of Italian philosophers, from the second half of the sixteenth and the first half of the seventeenth century. These philosophers are connected in a twofold manner with the movements already sketched of this transition period, first by an enthusiasm for nature which among them all partook in a greater or less degree of pantheism (Vanini _e. g._ gave to one of his writings the title “concerning the wonderful secrets of nature, the queen and goddess of mortals”), and second, by their connection with the systems of ancient philosophy. The best known of these philosophers are the following: _Cardanus_ (1501-1575), _Campanella_ (1568-1639), _Giordano Bruno_ (—1600), _Vanini_ (1586-1619.) They were all men of a passionate, enthusiastic and impetuous nature, unsteady and wild in character, restless and adventurous in life, men who were inspired by an eager impulse towards knowledge, but who were carried away by great fantasy, wildness of imagination, and a seeking after secret astrological and geomantic knowledge. For these reasons they also passed away, leaving no fruitful result behind. They were all persecuted by the hierarchy, and two of them (Bruno and Vanini) ended their lives at the stake. In their whole historical appearance they are like the eruption of a volcano, and are to be regarded more as forerunners and announcers than as beginners and founders of the new age of philosophy. The most important among them is _Giordano Bruno_. He reviewed the old idea of the Stoics, that the world is a living being, and that a world-soul penetrates it all. The content of his general thought is the profoundest enthusiasm for nature, and the plastic reason which is present in it. The reason is, according to him, the inner artist who shapes the matter and manifests himself in the forms of the universe. From the heart of the root or the germ he sends out the lobes, and from these again he evolves the shoots, and from the shoots the branches, until bud, and leaf, and blossom are brought forth. Every thing is arranged, adjusted, and perfected within. Thus the universal reason calls back from within the sap out of the fruits and flowers to the branches again, &c. The universe thus is an infinite living thing, in which every thing lives and moves after the most manifold way.

The relation of the reason to matter, Bruno determines wholly in the Aristotelian manner; both stand related to each other as form and matter, as actuality and potentiality, neither is without the other; the form is the inner impelling might of matter, and matter, as the unlimited possibility, as the capability for an infinite diversity of form, is the mother of all forms. The other side of Bruno’s philosophizing, his elaboration of the topics of Lullus, which occupies the greater part of his writings, has little philosophic interest, and we therefore pass it by.

8. JACOB BOEHME.—As Bacon among the English and Bruno among the Italians, so _Jacob Boehme_ is the index among the Germans of this transition period. Each one of these three indicates it in a way peculiar to his own nationality; Bacon as the herald of empiricism, Bruno as the representative of a poetic pantheism, and Boehme as the father of the theosophic mysticism. If we regarded alone the profoundness of his principle, Boehme should hold a much later place in the history of philosophy, but if we looked chiefly at the imperfect form of his philosophizing, his rank would be assigned to the mystics of the Middle Ages, while chronologically we must associate him with the German Reformation and the protestant elements that were nourished at that time. His true position is among the forerunners and prophets of the new age.

Jacob Boehme was born in 1575, in old Seidenburg, a village of upper Lusace, not far from Goerlitz. His parents were poor peasants. In his boyhood be took care of the cattle, and in his youth, after he had acquired the rudiments of reading and writing in a village school, he was sent to Goerlitz to learn the shoe-maker’s art. He finished his apprenticeship and settled down at Goerlitz in 1594 as master of his trade. Even in his youth he had received illuminations or mysterious revealings, which were subsequently repeated when his soul, striving for the truth, had become profoundly agitated by the religious conflicts of the age. Besides the Bible, the only books which Boehme read were some mystical writings of a theosophic and alchymistic content, _e. g._ those of Paracelsus. His entire want of culture is seen as soon as he undertakes to write down his thoughts, or, as he calls them, his illuminations. Hence the imperious struggle of the thought with the expression, which, however, not unfrequently rises to a dialectical acuteness and a poetic beauty. His first treatise, Aurora, composed in the year 1612, brought Boehme into trouble with the chief pastor in Goerlitz, Gregorious Richter, who publicly condemned the book from the pulpit, and even ridiculed the person of its author. The writing of books was prohibited him by a magistrate, a prohibition which Boehme observed for many years, till at length the command of the spirit was too mighty within him, and he took up again his literary labors. Boehme was a plain, quiet, modest and gentle man. He died in 1624.

To give an exhibition of his theosophy in a few words is very difficult, since Boehme, instead of clothing his thoughts in a logical form, dressed them only in pictures of the sense and obscure analogies, and often availed himself of the most arbitrary and singular modes of expression. A twilight reigns in his writings, as in a Gothic cathedral where the light falls through variegated windows. Hence the magic effect which he has made upon many hearts. The chief thought of his philosophizing is this, viz., that the distinguishing of the self from the not-self is the essential determination of spirit, and hence of God so far as God is to be apprehended as spirit. God, according to Boehme, is living spirit only at the time and in the degree in which he conceives the distinction within himself from himself, and is in this distinction object and consciousness. The distinction of God in himself is the only source of his and of all actuosity and spontaneity, the spring and fountain of that self-active life which produces consciousness out of itself. Boehme is inexhaustible in images by which this negativity in God, his self-distinguishing and self-renunciation to the world, may be made conceivable. The great expansion without end, he says, needs limitation and a compass in which it may manifest itself, for in expansion without limit there could be no manifestation, there must be a contraction and an enclosing, in order that a manifestation may arise. See, he says in another place, if the will were only of one kind, then would the soul have only one quality, and were an immovable thing, which would always lie still and never do any thing farther than one thing; in this there could be no joy, as also no art nor science of other things, and no wisdom; every thing would be a nothing, and there would be neither heart nor will for any thing, for there would be only the single. Hence it cannot be said that the whole God is in one will and essence, there is a distinction. Nothing can ever become manifest to itself without resistance, for if it has nothing resisting, it expends itself and never comes to itself again; but if it does not come to itself again except in that from which it has originally sprung, it thus knows nothing of its original condition. The above thought Boehme expresses when he says in his _Questionibus Theosophicis_; the reader should know that in yea and nay all things consist, whether divine, devilish, earthly, or whatever may be named. The one as the yea, is simple energy and love, and is the truth of God and God himself. But this were inconceivable, and there were neither delight, nor importance, nor sensibility, without the nay. The nay is thrown in the way of the yea, or of truth, in order that the truth may be manifest and something, in which there may be a contrarium, where eternal love may work and become sensitive and willing. There is nothing in the one which is an occasion for willing until the one becomes duplicated, and so there can be no sensation in unity, but only in duality. In brief, according to Boehme, neither knowledge nor consciousness is possible, without distinction, without opposition, without duplication; a thing becomes clear and an object of consciousness only through something else, through its own opposition identical with its own being. It was very natural to connect this thought of a unity distinguishing itself in itself, with the Christian doctrine of the Trinity, as Boehme has, in fact, repeatedly done when treating of the Divine life and its process of duplication. Schelling afterwards took up these ideas of Boehme and philosophically elaborated them.

If we should assign to the theosophy of Boehme a position in the development of later philosophy corresponding to the inner content of its principle, it would most properly be placed as a complement to the system of _Spinoza_. If Spinoza taught the flowing back of all the finite into the eternal one, Boehme, on the other hand, shows the procession of the finite from the eternal one, and the inner necessity of this procession, since the being of this one would be rather a not-being without such a self-duplication. Compared with Descartes, Boehme has at least more profoundly apprehended the conception of self-consciousness and the relation of the finite to God. But his historical position in other respects is far too isolated and exceptional, and his mode of statement far too impure, to warrant us in incorporating him anywhere in a series of systems developed continuously and in a genetic connection.

SECTION XXIV.

DESCARTES.

The beginner and founder of modern philosophy is _Descartes_. While he, like the men of the transition epoch just noticed, broke loose entirely from the previous philosophizing, and began his work wholly _de novo_, yet he did not content himself, like Bacon, with merely bringing out a new method, or like Boehme and his contemporaries among the Italians, with affirming philosophical views without a methodical ground. He went further than any of these, and making his standpoint one of universal doubt, he affirms a new, positive, and pregnant philosophical principle, from which he attempted logically to deduce the chief points of his system. The character and novelty of his principle makes him the beginner, and its inner fruitfulness the founder, of modern philosophy.

Rene Descartes (_Renatus Cartesius_) was born in 1596, at La Haye in Torraine. Possessing an independent property, he volunteered as a soldier in his twenty-first year, and served in the wars with the Dutch, the Bavarians, and the Imperialists. After this he travelled a good deal, and then abode a considerable time in Paris. In 1629 he left his native land, and betook himself to Holland, that he might there, undisturbed and unknown, devote himself to philosophy, and elaborate his scientific ideas. He spent twenty years in Holland, enduring much vexatious treatment from fanatical theologians, till in 1649 he accepted an invitation from Queen Christina of Sweden, to visit Stockholm, where he died in the following year.

The chief content of the Cartesian system may be seen condensed in the following epitome.

1. If science would have any thing fixed and abiding, it must begin with the primal ground of things; every presupposition which we may have cherished from infancy must be abandoned; in a word, we must doubt at every point to which the least uncertainty is attached. We must therefore doubt not only the existence of the objects of sense, since the senses so frequently deceive, but also the truths of mathematics and geometry—for, however evident the proposition may appear that two and three make five, or that the square has four sides, yet we cannot know but what God may have designedly formed us for erroneous judgments. It is therefore advisable to doubt every thing, in fact to deny every thing, to posit every thing as false.

2. But though we posit every thing as false to which the slightest doubt may be attached, yet we cannot deny one thing, viz., the truth that we, who so think, do exist. But rather from the very fact that I posit every thing as false, that I doubt every thing, is it manifest that I, the doubter, exist. Hence the proposition: I think, therefore I am (_cogito ergo sum_), is the first and most certain position which offers itself to every one attempting to philosophize. Upon this the most certain of all propositions, the certainty of all other knowledge depends. The objection of _Gassendi_ that the truth of existence follows from any other activity of man as well as from thinking, that I might just as well say: I go to walk, therefore I exist,—has no weight; for, of all my actions, I can be absolutely certain only of my thinking.

3. From the proposition I think, therefore, I am, the whole nature of the mind may be determined. When we examine who we are who hold every thing to be false that is distinct from ourselves, we see clearly that neither extension nor figure, nor any thing which can be predicated of body, but only thought, belongs to our nature. I am therefore only a thinking being, _i. e._ mind, soul, intelligence, reason. Thought is my substance. Mind can therefore be apprehended clearly and completely for itself alone, without any of those attributes which belong to body. Its conception contains nothing of that which belongs to the conception of body. It is therefore impossible to apprehend it through any sensuous representation, or to make an image of it: it apprehends itself only through the pure intelligence.

4. From the proposition _cogito ergo sum_, follows still farther the universal rule of all certainty. I am certain that I am a thinking being, what now is involved in the fact that I am certain of any thing? Whence comes this certainty? From no other source than the knowledge that this first proposition contains a clear conception of that which I affirm. I know of a certainty that I am, and I know any thing else only when I know it as certainly as I know that I am. Hence I may regard it as a universal rule, that every thing is true which I know clearly and determinately.
