The means employed by Nature to bring about the development of all the capacities of men is their antagonism in society, so far as this is, in the en… - Immanuel Kant

La sencillez y sobriedad de la naturaleza promueven y configuran en el hombre sólo nociones comunes y una tosca honestidad. La coacción artificial y la opulencia de la organización civil [de la sociedad] dan lugar a hombres ingeniosos y razonadores, si bien en ocasiones también a locos (Narren) y tramposos (Betrüger), y genera la sabia u honesta apariencia que permite carecer tanto de entendimiento como de honradez, siempre que el bello velo que el decoro extiende sobre las secretas dolencias (Gebrechen) de la cabeza o del corazón sea tupido y suficientemente tejido. — Immanuel Kant, Ensayo sobre las enfermedades de la cabeza

Every beginning is in time, and every limit of extension in space. Space and time, however, exist in the world of sense only. Hence phenomena are only limited in the world conditionally, the world itself, however, is limited neither conditionally nor unconditionally.

"The purpose of this critique of pure speculative reason consists in the attempt to change the old procedure of metaphysics, and to bring about a complete revolution after the example set by geometers and investigators of nature. This critique is a treatise on the method, not a system of the science itself; but nevertheless it marks out the whole plan of this science, both with regard to its limits and with regard to its inner organization. For it is peculiar to pure speculative reason that it is able, indeed bound, to measure its own powers according to the different ways in which it chooses its objects for thought, and to enumerate exhaustively the different ways of choosing its problems, thus tracing a complete outline of a system of metaphysics. This is due to the fact that, with regard to the first point, nothing can be attributed to objects in *a priori* knowledge, except what the thinking subject takes from within itself; while, with regard to the second point, pure reason, as far as its principles of knowledge are concerned, forms a separate and independent unity, in which, as in an organized body, every member exists for the sake of all the others, and all the others exist for the sake of the one, so that no principle can be safely applied in *one* relation unless it has been carefully examined in *all* its relations to the whole use of pure reason. Hence, too, metaphysics has this singular advantage, an advantage which cannot be shared by any other rational science which has to deal with objects (for *logic* deals only with the form of thought in general), that if by means of this critique it has been set upon the secure course of a science, it can exhaustively grasp the entire field of knowledge pertaining to it, and can thus finish its work and leave it to posterity as a capital that can never be added to, because it has to deal only with principles and with the limitations of their use, as determined by these principles themselves. And this completeness
