These processes are indeed essentially different in nature from the processes with which we are now concerned, yet the analogy between the two is almost perfect; and hence, in chemical analysis and synthesis, we find the best illustration of the nature of analysis and synthesis of notions or terms, by which--in a way very similar to the analysis and synthesis of material bodies--notions are analyzed into elementary notions, and these again synthesized into compound. § 109. Of The World Of Things And The World Of Thought.--The world of things is made up of actual things or substances; the world of thought, of concepts or notions. There is between the two a regular correspondence, i. e., a correspondence determined by invariable law, and yet the two are clearly distinct.
