Transcendental philosophy, which is about what it is possible to know, focuses less upon the objects themselves that are to be determined than upon the acts of knowledge that are constitutive of sciences, and is a philosophy of limits. The orientation of ontological and deontological divisions towards the happiness of the greatest number is obviously not the same, and could not possibly produce the same results, as the orientation given by a transcendental subject, which founds the necessary conditions for the possibility of both sciences and morals. The dialectical effects which lead reason to contradict itself on fundamental points, or to grant existence to what can only remain ideal are linked, in Kant, to some illusions about limits. Dialectics is linked to the lack of supervision which results in the reason pushing limits too far or in it's unduly, though inevitably, exceeding them.
