QUOTE : Every science presupposes faith in self, in our self-consciousness; presupposes faith in the accurate working of our senses; presupposes faith in the correctness of the laws of thought; presupposes faith in something universal hidden behind the special phenomena; presupposes faith in life; and especially presupposes faith in the principles, from which we proceed ; which signifies that<br />all these indispensable axioms, needed in a productive scientific investigation, do not come to us by proof, but are established in our judgment by our inner conception and given with our self-consciousness.
