The principal events in Christian Wolff's life are these: He was the son of a baker, and was born at Breslau in 1679. He first studied Theology and then Philosophy, and in 1707 he became Professor of Mathematics and Philosophy at Halle. Here the pietistic theologians, and more especially Lange, treated him in the basest manner. Piety did not trust this understanding; for piety, if it is true, embodies a content which is speculative in nature, and which passes beyond the understanding. As his opponents could make no headway by their writings, they resorted to intrigues. They caused it to be conveyed to King Frederick William I., the father of Frederick II., a rough man who took an interest in nothing but soldiers, that according to the determinism of Wolff, free will was impossible, and that soldiers could not hence desert of their own free will, but by a special disposition of God (pre-established harmony) a doctrine which, if disseminated amongst the military, would be extremely dangerous. The king, much enraged by this, immediately issued a decree that within forty-eight hours Wolff should leave Halle and the Prussian States, under penalty of the halter. Wolff thus left Halle on the 23rd of November, 1723. The theologians added to all this the scandal of preaching against Wolff and his philosophy, and the pious Franke thanked God on his knees in church for the removal of Wolff. But the rejoicings did not last long.
Wolff went to Cassel, was there immediately installed first professor in the philosophic faculty at Marburg, and at the same time made a member of the Academies of Science of London, Paris, and Stockholm. By Peter the First of Russia he was made Vice-President of the newly instituted Academy in St. Petersburg. Wolff was also summoned to Russia, but this invitation he declined; he received, however, an honorary post, he was made a Baron by the Elector of Bavaria, and, in short, loaded with public honours which, more especially at that time, though even now it is the case, were very much thought of by the general public, and which were too great not to make a profound sensation in Berlin. In Berlin a commission was appointed to pass judgment on the Wolffian philosophy - for this it had not been possible to eradicate - and it declared the same to be harmless, that is to say, free from all danger to state and religion; it also forbade the theologians to make it a subject of dispute, and altogether put an end to their clamour. Frederick William now issued a recall in very respectful terms to Wolff, who, however, hesitated to comply with it owing to his lack of confidence in its sincerity. On the accession of Frederick II. in 1740 he was again recalled in terms of the highest honour (Lange had meanwhile died), and only then did be comply.
Wolff became Vice-Chancellor of the University, but he outlived his repute, and his lectures at the end were very poorly attended. He died in 1754.(1)Like Tschirnhausen and Thomasius, Wolff wrote a great part of his works in his mother tongue, while Leibnitz for the most part wrote only in Latin or French. This is an important matter, for, as we have already noticed (pp. 114 and 150), it is only when a nation possesses a science in its own language that it can really be said to belong to it; and in Philosophy most of all this is requisite. For thought has in it this very moment of pertaining to self-consciousness or of being absolutely its own; when one's own language is the vehicle of expression, as when we talk of "Bestimmtheit"instead of "Determination," and "Wesen" instead of "Essenz," it is immediately present to our consciousness that the conceptions are absolutely its own; it has to deal with these at all times, and they are in no way foreign to it. The Latin language has a phraseology, a definite sphere and range of conception; it is at once taken for granted that when men write in Latin they are at liberty to be dull; it is impossible to read or write what men permit themselves to say in Latin. The titles of Wolff's philosophic works are perpetually of this nature: "Rational thoughts on the powers of the human understanding and their right uses in the knowledge of the truth," Halle, 1712, 8vo;"Rational thoughts on God, the world, and the soul of man, likewise on all things generally,"Frankfort and Leipzig, 1719; "On the action and conduct of men," Halle, 1720; "On Social Life,"Halle, 1720; "On the operations of Nature," Halle, 1723, and so on. Wolff wrote German and Latin quartos on every department of Philosophy, even on economics - twenty-three thick volumes of Latin, or about forty quartos altogether. His mathematical works make a good many more quartos. He brought into general use the differential and integral calculus of Leibnitz.
