stated, and to which Lysis was content with making allusion, on account of the secret of the mysteries that he was forced to respect.
It is this perfectibility manifested in Nature, which gives the affirmative proofs that I have promised, touching the way in which Providence removes with time the evils which afflict men. These are the proofs de facto. They cannot be challenged without absurdity. I know well that there have been men who, studying Nature within four walls, and considering its operations through the extremely narrow prism of their ideas, have denied that anything might be perfectible, and have asserted that the Universe was immobile because they have not seen it move; but there does not exist today a genuine observer, a naturalist whose learning is founded upon Nature, who does not invalidate the decision of these pretended savants, and who does not put perfectibility in the rank of the most rigorously demonstrated truths.
I shall not quote the ancients on a subject where their authority would be challenged; I shall even limit myself, to evade prolixities, to a small number of striking passages among the moderns. Leibnitz, who ought less than any other to admit perfectibility, since he had founded his system upon the existence of the best of worlds possible, has, however, recognized it in Nature, in advancing that all the changes which are operated there are the consequence of both; that everything tends toward its improvement, and that therefore the present is already teeming with the future.[1] Buffon, inclining strongly toward the system of atoms, ought also to be much opposed, and yet he has been unable to see that Nature, in general, tends far more toward life than toward death, and that it seems to be seeking to organize bodies as much as is possible.[2] The school of Kant has pushed the system of perfectibility as far as it
