ABSTRACT
This chapter establishes the worth of fundamental conceptions and of the axiomatic principles which people shall employ. The neo-hegelian, the follower of Kant, the sensationalist, though their respective standpoints are so widely divergent, are at one in declaring that the conceptions and principles in question are destitute of objective validity. Sensationalism refuses to admit this consciousness of a subject, and declares that people know nothing save a succession of states. Kant assures that by the very nature of the case it is impossible that people should know realities unmodified by the mind things as they are in themselves, noumena. The principle of causality Kant declares to be a synthetical a priori judgment. His division of analytical and synthetical judgments differed from that in use among the Aristotelian logicians. Kant's theory to shake conviction as to the validity of primary notions and the truth of those fundamental first principles which form the very basis of knowledge.
