The self, or the Ego, rests wholly on an illusion. Of course, with such premises, nothing can be said of the immortality of the soul. If the soul is only the compound of our notions, it necessarily ceases with the notions—that which is compounded of the movements of the body dies with those movements. There needs no further proof, than simply to utter these chief thoughts of Hume, to show that his scepticism is only a logical carrying out of Locke’s empiricism. Every determination of universality and necessity must fall away, if we derive our knowledge only from perceptions through the sense; these determinations cannot be comprised in sensation. SECTION XXX. CONDILLAC. The French took up the problem of carrying out the empiricism of Locke, to its ultimate consequences in sensualism and materialism. Although this empiricism had sprung up on English soil, and had soon become universally prevalent there, it was reserved for France to push it to the last extreme, and show that it overthrew all the foundations of moral and religious life. This final consequence of empiricism did not correspond to the English national character. But on the contrary, both the empiricism of Locke, and the scepticism of Hume, found themselves opposed in the latter half of the eighteenth century, by a reaction in the Scotch philosophy (_Reid_ 1701-1799, _Beattie_, _Oswald_, _Dugald Stewart_, 1753-1828). The attempt was here made to establish certain principles of truth as innate and immanent in the subject, which should avail both against the _tabula rasa_ of Locke, and the scepticism of Hume. These principles were taken in a thoroughly English way, as those of common sense, as facts of experience, as facts of the moral instinct and sound human understanding; as something empirically given, and found in the common consciousness by self-contemplation and reflection. But in France, on the other hand, there was such a public and social condition of things during the eighteenth century, that we can only regard the systems of materialism and egoistic moralism which here appeared, as the last practical consequences of the empirical standpoint,—to be the natural result of the universal desolation. The expression of a lady respecting the system of Helvetius is well known, that it uttered only the secret of all the world. Most closely connected with the empiricism of Locke, is the sensualism of the Abbé _Condillac_. Condillac was born at Grenoble, 1715. In his first writings he adhered to Locke, but subsequently passed beyond him, and sought to ground a philosophical standpoint of his own. He was elected a member of the French Academy in 1768, and died in 1780. His writings fill twenty-three volumes, and have their origin in a moral and religious interest.
