El mundo de ningún modo se hundirá porque haya menos hombres malos. - Immanuel Kant

Such is the genesis of these general convictions of mankind, so far as they depend on rational grounds; and this public property not only remains undisturbed, but is even raised to greater importance, by the doctrine that the schools have no right to arrogate to themselves a more profound insight into a matter of general human concernment than that to which the great mass of men, ever held by us in the highest estimation, can without difficulty attain, and that the schools should, therefore, confine themselves to the elaboration of these universally comprehensible and, from a moral point of view, amply satisfactory proofs.

Act only according to that maxim whereby you can at the same time will that it should become a universal law.

[It] is nevertheless better than the theological concept, of deriving morality from a divine, all-perfect will, not merely because we do not intuit this perfection, but can derive it solely from our concepts, of which morality is the foremost one, but because if we do not do this (which, if we did, would be a crude circle in explanation), the concept of his will that is left over to us, the attributes of the desire for glory and domination, bound up with frightful representations of power and vengeance, would have to make a foundation for a system of morals that is directly opposed to morality.
