The question of innate ideas has been often mooted in philosophy. As, however, the essential functions and different acts of thought, together with its several notions, are, properly speaking, nothing but the natural division of man’s cogitative faculty, it is not on their account necessary to suppose such a preliminary intercalation of general ideas into the human mind. And as little necessary is it, in order to explain the universal belief in the existence of a Deity, to suppose that there is in the minds of all men an implanted idea of God; for this would lead to the purely arbitrary hypothesis, of that which is so difficult to conceive--the pre-existence of the spirit or soul of man. And as no created beings can have an idea of God, but those to whom He vouchsafes to communicate it, and to accord a knowledge of His existence, so can He bestow this privilege the very instant He pleases, without the intervention of any innate idea expressly for that end. And yet I am disposed, and not, I think, without reason, to assume that man, as at present constituted, does possess one, though only one, species of inborn ideas, viz., an innate idea of death. This, as a false root of life, and a true mental contagion, produces a dead cogitation, and is the origin of all dead and dead-born notions. For this idea of death, whether hereditary or inoculated in the soul, is, as its peculiar but fundamental error, transferred by the mind of man to every object with which it comes in contact. And thus, in man’s dead cogitation, the surrounding world and all nature appears to him a similar lifeless and inert mass, so long as sitting beneath this shadow of spiritual death, his mind [_geist_] has not sufficient strength to work its way out of its dark prison-house into the light. For not at all without higher aid, and even with it only slowly and tardily, does man discover that all that is really and naturally dead is within himself, or learn to recognize it for what it truly is, a something eminently null and naught. Another species of this false and dead conception of nature presents itself under the form of multiplicity. In this view nature is represented as forming something like a vast sandhill, where, apart from the pile they thus form together and their aggregation in it, the several grains are supposed to have no connection with each other; while, however, they are so diligently counted, as if every thing depended on their right enumeration. But through the sieve of such an atomistic, which would break up the universe into a number of separate and absolute individualities, the sand will ever run, however often and painfully man may strive to reckon or to measure the infinity of these grains of nature. Mathematical calculation and measuring hold the same place in physical science that is held in every living language by conjugating and declining, and other grammatical rules, which, in truth, are but a species of mathematical formulæ.
