Part 21

3. The Encyclopedists had a more decidedly sceptical relation to the principles and the basis of spiritualism. The philosophical Encyclopedia established by _Diderot_ (1713-1784), and published by him in connection with d’Alembert, is a memorable monument of the ruling spirit in France in the time before the revolution. It was the pride of France at that age, because it expressed in a splendid and universally accessible form the inner consciousness of the French people. With the keenest wit it reasoned away law from the state, and freedom from morality, and spirit and God from nature, though all this was done only in scattered, and, for the most part, timorous intimations. In Diderot’s independent writings we find talent of much philosophic importance united with great earnestness. But it is very difficult to fix and accurately to limit his philosophic views, since they were very gradually formed, and Diderot expressed them always with some reserve and accommodation. In general, however, it may be remarked, that in the progress of his speculations he constantly approached nearer the extreme of the philosophical direction of his age. In his earlier writings a Deist, he afterwards avowed the opinion that every thing is God. At first defending the immateriality and immortality of the soul, he expressed himself at a later period decidedly against these doctrines, affirming that the species alone has an abiding being while the individual passes away, and that immortality is nothing other than to live in the thoughts of coming generations. But Diderot did not venture to the real extreme of logical materialism; his moral earnestness restrained him from this.

4. The last word of materialism was spoken with reckless audacity by _La Mettrie_ (1709-1751), a contemporary of Diderot: every thing spiritual is a delusion, and physical enjoyment is the highest end of men. Faith in the existence of a God, says La Mettrie, is just as groundless as it is fruitless. The world will not be happy till atheism becomes universally established. Then alone will there be no more religious strife, then alone will theologians, the most odious of combatants, disappear, and nature, poisoned at present by their influence, will come again to its rights. In reference to the human soul, there can be no philosophy but materialism. All the observation and experience of the greatest philosophers and physicians declare this. Soul is nothing but a mere name, which has a rational signification only when we understand by it that part of our body which thinks. This is the brain, which has its muscles of thought, just as the limbs have their muscles of motion. That which gives man his advantage over the brutes is, first, the organization of his brain, and second, its capacity for receiving instruction. Otherwise, is man a brute like the beasts around him, though in many respects surpassed by these. Immortality is an absurdity. The soul perishes with the body of which it forms a part. With death every thing is over, _la farce est jouée_! The practical and selfish application of all this is—let us enjoy ourselves as long as we exist, and not throw away any satisfaction we can attain.

5. The _Systéme de la Nature_ afterwards attempted to elaborate with greater earnestness and scientific precision, that which had been uttered so superficially and so superciliously by La Mettrie, viz., the doctrine that matter alone exists, while mind is nothing other than matter refined.

The _Systéme de la Nature_ appeared in London under a fictitious name in 1770. It was then published as a posthumous work of Mirabaud, late secretary of the Academy. It doubtless had its origin in the circle which was wont to assemble with Baron Holbach, and of which Diderot, Grimm, and others formed a part. Whether the Baron Holbach himself, or his tutor Lagrange is the author of this work, or whether it is the joint production of a number, cannot now be determined. The _Systéme de la Nature_ is hardly a French book: the style is too heavy and tedious.

There is, in fact, nothing but matter and motion, says this work. Both are inseparably connected. If matter is at rest, it is only because hindered in motion, for in its essence it is not a dead mass. Motion is twofold, attraction and repulsion. The different motions which we see are the product of these two, and through these different motions arise the different connections and the whole manifoldness of things. The laws which direct in all this are eternal and unchangeable.—The most weighty consequences of such a doctrine are:

(1.) _The materiality of man._ Man is no twofold being compounded of mind and matter, as is erroneously believed. If the inquiry is closely made what the mind is, we are answered, that the most accurate philosophical investigations have shown, that the principle of activity in man is a substance whose peculiar nature cannot be known, but of which we can affirm that it is indivisible, unextended, invisible, &c. But now, who should conceive any thing determinate in a substance which is only the negation of that which gives knowledge, an idea which is peculiarly only the absence of all ideas? Still farther, how can it be explained upon such a hypothesis, that a substance which itself is not material can work upon material things; and how can it set these in motion, since there is no point of contact between the two? In fact, those who distinguish their soul from their body, have only to make a distinction between their brain and their body. Thought is only a modification of our brain, just as volition is another modification of the same bodily organ.

(2.) Another chimera, the belief in the being of a God, is connected with the twofold division of man into body and soul. This belief arises like the hypothesis of a soul-substance, because mind is falsely divided from matter, and nature is thus made twofold. The evil which men experienced, and whose natural cause they could not discover, they assigned to a deity which they imagined for the purpose. The first notions of a God have their source therefore in sorrow, fear, and uncertainty. We tremble because our forefathers for thousands of years have done the same. This circumstance awakens no auspicious prepossession. But not only the rude, but also the theological idea of God is worthless, for it explains no phenomenon of nature. It is, moreover, full of absurdities, for, since it ascribes moral attributes to God, it renders him human; while on the other hand, by a mass of negative attributes, it seeks to distinguish him absolutely from every other being. The true system, the system of nature, is hence atheistic. But such a doctrine requires a culture and a courage which neither all men nor most men possess. If we understand by the word atheist one who considers only _dead_ matter, or who designates the _moving power_ in nature with the name God, then is there no atheist, or whoever would be one is a fool. But if the word means one who denies the existence of a spiritual being, a being whose attributes can only be a source of annoyance to men, then are there indeed atheists, and there would be more of them, if a correct knowledge of nature and a sound reason were more widely diffused. But if atheism is true, then should it be diffused. There are, indeed, many who have cast off the yoke of religion, who nevertheless think it is necessary for the common people in order to keep them within proper limits. But this is just as if we should determine to give a man poison lest he should abuse his strength. Every kind of Deism leads necessarily to superstition, since it is not possible to continue on the standpoint of pure deism.

(3.) With such premises the freedom and immortality of the soul both disappear. Man, like every other substance in nature, is a link in the chain of necessary connection, a blind instrument in the hands of necessity. If any thing should be endowed with self-motion, that is, with a capacity to produce motion without any other cause, then would it have the power to destroy motion in the universe; but this is contrary to the conception of the universe, which is only an endless series of necessary motions spreading out into wider circles continually. The claim of an individual immortality is absurd. For to affirm that the soul exists after the destruction of the body, is to affirm that a modification of a substance can exist after the substance itself has disappeared. There is no other immortality than to live in the remembrance of posterity.

(4.) The practical consequences of these principles are in the highest degree favorable for the system of nature, the utility of any doctrine being ever the first criterion of its truth. While the ideas of theologians are productive only of disquiet and anxiety to man, the system of nature frees him from all such unrest, teaches him to enjoy the present moment, and to quietly yield to his destiny, while it gives him that kind of apathy which every one must regard as a blessing. If morality would be active, it can rest only upon self-love and self-interest; it must show man whither his well-considered interest would lead him. He is a good man who gains his own interest in such a way that others will find it for their interest to assist him. The system of self-interest, therefore, demands the union of men among each other, and hence we have true morality.

The logical dogmatic materialism of the _Système de la Nature_ is the farthest limit of an empirical direction in philosophy, and consequently closes that course of the development of a one-sided realism which had begun with Locke. The attempt first made by Locke to explain and derive the ideal world from the material, ended in materialism with the total reduction of every thing spiritual to the material, with the total denial of the spiritual. We must now, before proceeding farther, according to the classification made § XXVII., consider the idealistic course of development which ran parallel with the systems of a partial realism. At the head of this course stands _Leibnitz_.

SECTION XXXIII.

LEIBNITZ.

As empiricism sprang from the striving to subject the intellectual to the material, to materialize the spiritual, so on the other hand, idealism had its source in the effort to spiritualize the material, or so to apprehend the conception of mind that matter could be subsumed under it. To the empiric-sensualistic direction, mind was nothing but refined matter, while to the idealistic direction matter was only degenerated (_vergröbert_) mind (“a confused notion,” as Leibnitz expresses it). The former, in its logical development, was driven to the principle that only material things exist, the latter (as with Leibnitz and Berkeley) comes to the opposite principle, that there are only souls and their ideas. For the partial realistic standpoint, material things were the truly substantial. But for the idealistic standpoint, the substantial belongs alone to the intellectual world, to the Egos. Mind, to the partial realism, was essentially void, a _tabula rasa_, its whole content came to it from the external world. But a partial idealism sought to carry out the principle that nothing can come into the mind which had not at least been preformed within it, that all its knowledge is furnished it by itself. According to the former view knowledge was a passive relation, according to the latter was it wholly active. While, in fine, a partial realism had attempted to explain the becoming in nature for the most part through real, _i. e._ through mechanical motives (_l’homme machine_ is the title of one of la Mettrie’s writings), idealism had sought an explanation of the same through ideal motives, _i. e._ teleologically. While the former had made its prominent inquiry for moving causes, and had, indeed, often ridiculed the search for a final cause; it is final causes toward which the latter directs its chief aim. The mediation between mind and matter, between thought and being, will now be sought in the final cause, in the teleological harmony of all things (_pre-established harmony_). The standpoint of Leibnitz may thus be characterized in a word.

_Gottfried Wilhelm Leibnitz_ was born in 1646, at Leipsic, where his father was professor. Having chosen the law as his profession, he entered the university in 1661, and in 1663 he defended for his degree of doctor in philosophy, his dissertation _de principio individui_, a theme well characteristic of the direction of his later philosophizing. He afterwards went to Jena, and subsequently to Altdorf, where he became doctor of laws. At Altdorf he was offered a professorship of jurisprudence, which he refused. The rest of his life was unsettled and desultory, spent for the most part in courts, where, as a versatile courtier, he was employed in the most varied duties of diplomacy. In the year 1672 he went to Paris, in order to induce Louis XIV. to undertake the conquest of Egypt. He subsequently visited London, whence he was afterwards called to Hanover, as councillor of the Duke of Brunswick. He received later a post as librarian at Wolfenbüttel, between which place and Hanover he spent the most of his subsequent life, though interrupted with numerous journeys to Vienna, Berlin, etc. He was intimately associated with the Prussian Electress, Maria Charlotte, a highly talented woman, who surrounded herself with a circle of the most distinguished scholars of the time, and for whom Liebnitz wrote, at her own request, his _Theodicée_. In 1701, after Prussia had become a kingdom, an academy was established at Berlin, through, his efforts, and he became its first president. Similar, but fruitless attempts were made by him to establish academies in Dresden and Vienna. In 1711 the title of imperial court councillor, and a baronage, was bestowed upon him by the emperor Charles VI. Soon after, he betook himself to Vienna, where he remained a considerable period, and wrote his Monadology, at the solicitation of Prince Eugene. He died in 1716. Next to Aristotle, Leibnitz was the most highly gifted scholar that had ever lived; with the richest and most extensive learning, he united the highest and most penetrating powers of mind. Germany has reason to be proud of him, since, after Jacob Boehme, he is the first philosopher of any note among the Germans. With him philosophy found a home in Germany. It is to be regretted that the great variety of his efforts and literary undertakings, together with his roving manner of life, prevented him from giving any connected exhibition of his philosophy. His views are for the most part developed only in brief and occasional writings and letters, composed frequently in the French language. It is hence not easy to state his philosophy in its internal connection, though none of his views are isolated, but all stand strictly connected with each other. The following are the chief points:

1. THE DOCTRINE OF MONADS.—The fundamental peculiarity of Leibnitz’s theory is its opposition to Spinozism. Substance, as the indeterminate universal, was with Spinoza the only positive. With Leibnitz also the conception of substance lay at the basis of his philosophy, but his definition of it was entirely different. While Spinoza had sought to exclude from his substance every positive determination, and especially all acting, and had apprehended it simply as pure being, Leibnitz viewed it as living activity and active energy, an example for which might be found in a stretched bow, which moved and straightened itself through its own energy as soon as the external hindrance was removed. That this active energy forms the essence of substance is a principle to which Leibnitz ever returns, and from which, in fact, all the other chief points in his philosophy may be derived. From this there follow at the outset two determinations of substance directly opposed to Spinozism; first, that it is a single being, a monad; and second, that there are a multiplicity of monads. The first follows because substance, in so far as it exercises an activity similar to an elastic body, is essentially an excluding activity, or repulsion; the conception of an individual or a monad being that which excludes another from itself. The second follows because the existence of one monad involves the existence of many. The conception of one individual postulates other individuals, which stand over against the one as excluded from it. Hence the fundamental thesis of the Leibnitz philosophy in opposition to Spinozism is this, viz., there is a multiplicity of individual substances or monads.

2. THE MONADS MORE ACCURATELY DETERMINED.—The monads of Leibnitz are similar to atoms in their general features. Like these they are corpuscular units, independent of any external influence, and indestructible by any external power. But notwithstanding this similarity, there is an important and characteristic difference between the two. First, the atoms are not distinguished from each other, they are all qualitatively alike; but each one of the monads is different in quality from every other, every one is a peculiar world for itself, every one is different from every other. According to Leibnitz, there are no two things in the world which are exactly alike. Secondly, atoms can be considered as extended and divisible, but the monads are metaphysical points, and actually indivisible. Here, lest we should stumble at this proposition (for an aggregate of unextended monads can never give an extended world), we must take into consideration Leibnitz’s view of space, which, according to him, is not something real, but only confused, subjective representation. Thirdly, the monad is a representative being. With the atomists such a determination would amount to nothing, but with Leibnitz it has a very important part to play. According to him, in every monad, every other is reflected; every monad is a living mirror of the universe, and ideally contains the whole within itself as in a germ. In thus mirroring the world, however, the monad is not passive but spontaneously self-active: it does not receive the images which it mirrors, but produces them spontaneously itself, as the soul does a dream. In every monad, therefore, the all-seeing and all-knowing one might read every thing, even the future, since this is potentially contained in the present. Every monad is a kind of God. (_Parvus in suo genere Deus._)

3. THE PRE-ESTABLISHED HARMONY.—The universe is thus the sum of all the monads. Every thing, every composite, is an aggregate of monads. Thus every bodily organism is not one substance, but many, it is a multiplicity of monads, like a machine which is made up of a number of distinct pieces of mechanism. Leibnitz compared bodies to a fish-pond, which might be full of living elements, though dead itself. The ordinary view of things is thus wholly set aside; the truly substantial does not belong to bodies, _i. e._ to the aggregates, but to their original elements. Matter, in the vulgar sense, as something conceived to be without mind, does not at all exist. How now must the inner connection of the universe be conceived? In the following way. Every monad is a representative being, and at the same time, each one is different from every other. This difference, therefore, depends alone upon the difference of representation: there are just as many different degrees of representation as there are monads, and these degrees may be fixed according to some of their prominent stages. The representations may be classified according to the distinction between confused and distinct knowledge. Hence a monad of the lowest rank (a monad _toute nue_) will be one which _simply_ represents, _i. e._ which stands on the stage of most confused knowledge. Leibnitz compares this state with a swoon, or with our condition in a dreamy sleep, in which we are not without representations, (notions)—for otherwise we could have none when awaking—but in which the representations are so numerous that they neutralize each other and do not come into the consciousness. This is the stage of inorganic nature. In a higher rank are those monads in which the representation is active as a formative vital force, though still without consciousness. This is the stage of the vegetable world. Still higher ascends the life of the monad when it attains to sensation and memory, as is the case in the animal kingdom. The lower monads may be said to sleep, and the brute monads to dream. When still farther the soul rises to reason or reflection, we call it mind, spirit.—The distinction of the monads from each other is, therefore, this, that each one, though mirroring the whole and the same universe in itself, does it from a different point of view, and, therefore, differently, the one more, and the rest less perfectly. Each one is a different centre of the world which it mirrors. Each one contains the whole universe, the whole infinity within itself, and in this respect is like God, the only difference being that God knows every thing with perfect distinctness, while the monad represents it confusedly, though one monad may represent it more confusedly than another. The limitation of a monad does not, therefore, consist in its containing less than another or than God, but only in its containing more imperfectly or in its representing less distinctly.—Upon this standpoint the universe, in so far as every monad mirrors one and the same universe, though each in a different way, represents a drama of the greatest possible difference, as well as of the greatest possible unity and order, _i. e._ of the greatest possible perfection, or the _absolute harmony_. For distinction in unity is harmony.—But in still another respect the universe is a system of harmony. Since the monads do not work upon each other, but each one follows only the law of its own being, there is danger lest the inner harmony of the universe may be disturbed. How is this danger removed? Thus, viz., every monad mirrors the whole and the same universe. The changes of the collected monads, therefore, run parallel with each other, and in this consists the harmony of all as pre-established by God.

4. THE RELATION OF THE DEITY TO THE MONADS.—What part does the conception of God play in the system of Leibnitz? An almost idle one. Following the strict consequences of his system, Leibnitz should have held to no proper theism, but the harmony of the universe should have taken the place of the Deity. Ordinarily he considers God as the sufficient cause of all monads. But he was also accustomed to consider the final cause of a thing as its sufficient cause. In this respect, therefore, he almost identifies God and the absolute final cause. Elsewhere he considers the Deity as a simple primitive substance, or as the individual primitive unity. Again, he speaks of God as a pure immaterial actuality, _actus purus_, while to the monads belongs matter, _i. e._ restrained actuality, striving, _appetitio_. Once he calls him a monad, though this is in manifest contradiction with the determinations otherwise assigned him. It was for Leibnitz a very difficult problem to bring his monadology and his theism into harmony with each other, without giving up the premises of both. If he held fast to the substantiality of the monads, he was in danger of making them independent of the Deity, and if he did not, he could hardly escape falling back into Spinozism.
