We have already considered the several processes of objective or concrete thinking, and the products which they evolve. The processes are analysis; generalization; classification; judgment, in the two forms of definition and division; and reasoning, by deduction and induction--giving us as their products, the concept; the class; the proposition; the argument; and the principle or law. The combination of these several processes and their results in a complex result or product, is scientific arrangement, and the product is the system. Scientific arrangement or method may be defined in general, as the gathering of individual objects into a synthetic whole, by any one of the analyses and generalizations of thought. When any number of such objects are united into such a whole, that whole may, in a certain sense, be called a system. This is not, however, the usual signification of the term. We employ it in this sense simply to call attention to the truth, that the process of classification is the beginning of systemization. This is the first condition or step of the synthetic process which terminates in the system proper. (PsycINFO Database Record (c) 2016 APA, all rights reserved)
