The object, therefore, of philosophy is the inner mental life (geistige Leben), not merely this or that individual faculty in any partial direction, but man’s spiritual life with all its rich and manifold energies. With respect to form and method: the philosophy of life sets out from a single assumption—that of life, or, in other words, of a consciousness to a certain degree awakened and manifoldly developed by experience—since it has for its object, and purposes to make known the entire consciousness, and not merely a single phase of it. Now, such an end would be hindered rather than promoted by a highly elaborate or minutely exhaustive form, and a painfully artificial method; and it is herein that the difference lies between a philosophy of life and the philosophy of the school. If philosophy be regarded merely as one part of a general scientific education, then is the instruction in method (whether under the old traditionary name of Logic or any other) the chief point to be regarded. For such a mere elementary course, passing over, or at least postponing for a while the consideration of the matter, as possessing as yet but a very remote interest for the student, and, in the default of an adequate internal experience of his own, incapable of being understood by him, concerns itself rather with the practice of methodical thought, both as necessary for the future, and as applicable to all matters. But the preliminary exercise in philosophical thinking is only the introduction to philosophy, and not philosophy itself. This school-teaching of philosophy might, perhaps, be rendered productive of the most excellent consequences, if only it were directed to the history of the human intellect. What could be more interesting than a history which should enter into the spirit, and distinctly embody the various systems which the inventive subtilety of the Greeks gave birth to, or which, taking a still wider range, should embrace the science of the Egyptians, and some Asiatic nations, and illustrate the no less wonderful nor less manifold systems of the Hindoos—those Greeks of the primeval world? But this, perhaps, would be to encroach upon the peculiar domain of erudition, and might, moreover, fail to furnish equal interest for all; and, at any rate, the history of philosophy is not philosophy itself.

Now, the distinction between the philosophy of life and the philosophy of the school will appear in very different lights, according to the peculiarity of view which predominates in the several philosophical systems. That species of philosophy which revolves in the dialectical orbit of abstract ideas, according to its peculiar character, presupposes and requires a well-practiced talent of abstraction, perpetually ascending through higher grades to the very highest, and even then boldly venturing a step beyond. In short, as may be easily shown in the instance of modern German science, the being unintelligible is set up as a kind of essential characteristic of a true and truly scientific philosophy. I, for my part, must confess that I feel a great distrust of that philosophy which dwells in inaccessible light, where the inventor indeed asserts of himself, that he finds himself in an unattainable certainty and clearness of insight, giving us all the while to understand thereby that he does see well enough how, of all other mortals, scarcely any, or, perhaps, strictly speaking, no one, understands or is capable of understanding him. In all such cases it is only the false light of some internal ignis fatuus that produces this illusion of the unintelligible, or, rather, of nonsense. In this pursuit of wholly abstract and unintelligible thought, the philosophy of the school is naturally enough esteemed above every other, and regarded as pre-eminently the true science—i.e., the unintelligible.

In such a system a philosophy of life means nothing more than a kind of translation of its abstruser mysteries into a more popular form, and an adaptation of them to the capacity of ordinary minds. But even such popular adaptations, though evincing no common powers of language and illustration, in spite of their apparent clearness, when closer examined, are found as unintelligible as the recondite originals. For, inasmuch as the subject-matter of these abstract speculations was, from the very first, confused and unintelligible, it was consequently incapable of being made clear even by the most perspicuous of styles. But the true living philosophy has no relation or sympathy with this continuous advance up to the unintelligible heights of empty abstraction. Since the objects it treats of are none other than those which every man of a cultivated mind, and, in any degree accustomed to observe his own consciousness, both has and recognizes within himself, there is nothing to prevent its exposition being throughout clear, easy, and forcible. Here the relation is reversed. In such a system the philosophy of life is the chief and paramount object of interest; while the philosophy of the school, or the scientific teaching of it in the schools, however necessary and valuable in its place, is still, as compared with the whole thing itself, only secondary and subordinate. In the philosophy of life, moreover, the method adopted must also be a living one. Consequently it is not, by any means, a thing to be neglected. But still it need not to be applied with equal rigor throughout, or to appear prominently in every part, but, on all occasions, must be governed in these respects by what the particular end in view may demand.

A few illustrations, drawn from daily experience, will, perhaps, serve to explain my meaning. Generally speaking, the most important arts and pursuits of life are ultimately based on mathematics. This science furnishes them, as it were, with the method they observe; but it is not practicable, nor, indeed, has man the leisure, to revert on every occasion, with methodical exactness, to these elements, but, assuming the principles to be well known and admitted, he attends rather to the results essential to the end he has in view. The economical management of the smallest as well as of the largest household, rests, in the end, on the elementary principles of arithmetic; but what would come of it if, on every occasion, we were to go back to the simple “one-times-one” of the multiplication table, and reflected upon and sought for the proofs that the principle is really valid and can confidently be relied on in practice? In the same way the art of war is founded on geometry; but when the general arranges his troops for battle, does he consult his Euclid to satisfy himself of the correctness and advantages of his position? Lastly, when the astronomer, whose vocation is pre-eminently dependent on accurate calculation, when he would make us acquainted with the phenomena of the sidereal heavens, confines himself almost entirely to them, without wearying those whom he wishes to interest, with the complicated reckonings which, however, in all probability, he was obliged himself to go through. With all these arts and pursuits of practical life, the intellectual business of thinking—of such thinking at least as is common to most men—and of communicating thought, has a sort of affinity and resemblance. For, unquestionably, it is one among the many problems of philosophy to establish a wise economy and prudent stewardship of that ever-shifting mass of incoming and outgoing thoughts which make up our intellectual estate and property. And this is the more necessary the greater are the treasures of thought possessed by our age. For, in the highly rapid interchange of and traffic in ideas, which is carrying on, the receipts and disbursements are not always duly balanced. There is much cause, therefore, to fear lest a thoughtless and lavish dissipation of the noblest mental endowments should become prevalent, or a false and baseless credit-system in thought spring up amid an absolute deficiency of a solid and permanent capital safely invested in fundamental ideas and lasting truths. As for the second simile: I should, by all means, wish to gain a victory, not indeed for you, but with you, over some of the many errors and many semblances of thought, which are, however, but cheats and counterfeits which distract the minds of the present generation, disturb the harmony of life, and banish peace even from the intellectual world. And as respects the third illustration: I should indeed rejoice as having, in a great measure, attained my object, if only I shall succeed in directing your attention to some star in the higher region of intellect, which hitherto was either totally unknown, or, at least, never before fully observed.

But above all, I think it necessary to observe further, that in the same way as philosophy loses sight of its true object and appropriate matter, when either it passes into and merges in theology, or meddles with external politics, so also does it mar its proper form when it attempts to mimic the rigorous method of mathematics. In the middle of the last century scarcely was there to be found a German manual for any of the sciences that did not ape the mathematical style, and where every single position in the long array of interminable paragraphs did not conclude with the solemn act of demonstrative phraseology. But it is also well known that the philosophy which was propounded in this inappropriate form and method was crammed full of, nay, rather, was hardly any thing more than a tissue of arbitrary, now forgotten, hypotheses, which have not brought the world at all nearer to the truth—not at least to that truth which philosophy is in search of, and which is something higher than a mere example of accurate computation.

And even in the present day—although, indeed, the application is made in a very different way from formerly—German philosophy is any thing but free from those algebraic formularies, in which all things, even the most opposite, admit of being comprised and blended together. But, be it as it may, this elaborate structure of mechanical demonstration can never produce a true, intrinsic, and full conviction. The method which philosophy really requires is quite different, being absolutely internal and intellectual (geistige). As in a correct architectural structure it is necessary that all its parts should be in unison, and such as the eye can take in easily and agreeably, so in every philosophical communication, the solid simple basis being laid, the arrangement of all the parts, and the careful rejection and exclusion of all foreign matter, is the most essential point, both for internal correctness and external perspicuity. But, in truth, the matter in hand bears a far closer resemblance and affinity to natural objects which live and grow, than to any lifeless edifice of stone; to a great tree, for instance, nobly and beautifully spreading out on all sides in its many arms and branches. As such a tree strikes the hasty and passing glance, it forms a somewhat irregular and not strictly finished whole; there it stands, just as the stem has shot up from the root, and has divided itself into a certain number of branches, and twigs, and leaves, which livingly move backward and forward in the free air. But examine it more closely, and how perfect appears its whole structure! how wonderful the symmetry, how minutely regular the organization of all its parts, even of each little leaf and delicate fiber! In the same way will the ever-growing tree of human consciousness and life appear in philosophy, whenever it is not torn from its roots and stripped of its leaves by a pretended wisdom, but is vividly apprehended by a true science, and exhibited and presented to the mind in its life and its growth.

Not only, however, the arrangement of the whole, but also the connection of the several parts of a philosophical treatise or development, is of a higher kind than any mere mechanical joining, such, for instance, as that by which two pieces of wood are nailed or glued together. If I must illustrate this connection by a simile from animated nature, the facts of magnetism will best serve my purpose. Once magnetically excited, the iron needle comes into invisible contact and connection with the whole globe and its opposite poles; and this magnetic clew has guided the bold circumnavigator into new and unknown regions of the world. Now, the intrinsic vital coherence of the several thoughts of philosophy resembles this magnetic attraction; and no such rude, mechanical, and, in fact, mere external conjunction of thought, like that lately alluded to, can satisfy the requirements of philosophical connection.

But the supreme intrinsic unity of philosophical thought, or of a philosophical series of ideas, is quite different from every thing hitherto mentioned. It belongs not to nature, but to life; it is not derived from the latter by way of figure or illustration, but is a part and constituent of it, and goes to the very root and soil of the moral life. What I mean is, the unity of sentiment—the fixed character, remaining ever the same and true to itself—the inner necessary sequence of the thoughts—which, in life no less than in the system and philosophical theory, invariably makes a great and profound impression on our minds, and commands our respect, even when it does not carry along with it our convictions. This, however, is dependent on no form, and no mere method can attain to it. How often, for instance, in some famous political harangue, which perhaps the speaker, like the rhapsodist of old, poured forth on the spur of the moment, do we at once recognize and admire this character in the thoughts, this consistency of sentiment? How often, on the contrary, in another composed with the most exquisite research and strict method, and apparently a far more elaborate and finished creation of the intellect, we have only to pierce through the systematic exterior to find that it is nothing but an ill-connected and chance-medley of conflicting assumptions and opinions taken from all quarters, and the crude views of the author himself, devoid of all solidity, and resting on no firm basis, without character, and wholly destitute of true intrinsic unity?

If now, in the present course of Lectures, I shall succeed in laying before you my subject in that clearness and distinctness which are necessary to enable you to comprehend the whole, and, while taking a survey of it, to judge of the agreement of the several parts, you will find, I trust, no difficulty in discovering the fundamental idea and sentiment. And further, I would venture to entreat you not to judge hastily of this sentiment from single expressions, and least of all at the very outset, but, waiting for its progressive development, to judge of it on the whole. Lastly, I would also indulge a hope that the views of an individual thinker, if perspicuously enunciated, may, even where they fail of conviction, and though points of difference still subsist, produce no revolting impression on your minds; but, by exercising a healing influence on many a rankling wound in thought and life, produce among us some of the fairest fruits of true philosophy.

Hitherto we have been considering, first of all, the object and proper sphere of the philosophy of life; and, secondly, its appropriate form of communication, as well as all other methods which are alien and foreign to it. Of great and decisive importance for the whole course and further development of philosophical inquiry is it to determine, in the next place, the starting-point from which it ought to set out. It will not do to believe that we have found this in any axiom or postulate such as are usually placed at the head of a system. For such a purpose we must rather investigate the inmost foundation—the root out of which springs the characteristic feature of a philosophical view. Now, in the philosophy of life the whole consciousness, with all its different phases and faculties, must inevitably be taken for the foundation, the soul being considered as the center thereof. This simple basis being once laid, it may be further developed in very different ways. For it is, I might almost say, a matter of indifference from what point in the circumference or periphery we set out in order to arrive at the center, with the design of giving a further development to this as the foundation of the whole. But in order to illustrate this simple method of studying life from its true central point, which is intermediate between the two wrong courses already indicated, and in order to make, by contrast, my meaning the plainer, I would here, in a few words, characterize the false starting-point from which the prevailing philosophy of a day—whether that of France in the eighteenth century or the more recent systems of Germany—has hitherto, for the most part, proceeded. False do I call it, both on account of the results to which it has led, and also of its own intrinsic nature. In one case as well as in the other, the starting-point was invariably some controverted point of the reason—some opposition or other to the legitimacy of the reason—under which term, however, little else generally was understood than an opposition of the reason itself to some other principle equally valid and extensive. The principal, or, rather, only way which foreign philosophy took in this pursuit, was to reduce every thing to sensation as opposed to reason, and to derive every thing from it alone, so as to make the reason itself merely a secondary faculty, no original and independent power, and ultimately nothing else than a sort of chemical precipitate and residuum from the material impressions.[3] But however much may be conceded to these and to the external senses, and however great a share they may justly claim in the whole inner property of the thinking man, still it is evident that the perception of these sensuous impressions, the inner coherence—in short, the unity of the consciousness in which they are collected—can never, as indeed it has often been objected on the other side, have come into the mind from without. This was not, however, the end which this doctrine had exclusively, or even principally, in view. The ultimate result to which they hoped to come by the aid of this premise was simply the negation of the suprasensible. Whatever in any degree transcends the material impression, or sensuous experience, as well as all possible knowledge of, and faith therein, not merely in respect to a positive religion, but absolutely whatever is noble, beautiful, and great—whatever can lead the mind to, or can be referred to a something suprasensible and divine—all this, wherever it may be found, whether in life or thought, in history or in nature—ay, even in art itself—it was the ultimate object of this foreign philosophy to decry, to involve in doubt, to attack and to overthrow, and to bring down to the level of the common and material, or to plunge it into the skeptical abyss of absolute unbelief. The first step in this system was a seeming subordination of reason to sensation, as a derivative of it—a mere slough which it throws off in its transformations. Afterward, however, the warfare against the suprasensible was waged entirely with the arms of reason itself. The reason, indeed, which supplied these weapons was not one scientifically cultivated and morally regulated, but thoroughly sophistical and wholly perverted, which, however, put into requisition all the weapons of a brilliant but skeptical wit, and moved in the ever-varied turnings of a most ingenious and attractive style. Here, where the question was no longer the abrogation of any single dogma of positive religion, but where the opposition to the divine had become the ruling tendency of philosophy, it is not easy to refrain from characterizing it as atheistical—what, indeed, in its inmost spirit it really was, and also historically proved itself by its results.
