Science, Dewey remarks in introducing this essay, is a systematized body of knowledge. Knowledge may be taken either as a body of facts or as a process of arranging a body of facts; as results or the acquiring of results. The latter phase of science is the more important. "As used in this article, 'scientific' means regular methods of controlling the formation of judgments regarding some subject-matter."[204] In the scientific attitude, beliefs are looked upon as _conclusions_, and as conclusions they look in two directions. They look backward towards the ground from which they are empirically derived, and which renders them valid, and they look forward, as meaning, to being the ground from which further conclusions can be deduced. "So far as we engage in this procedure, we look at our respective acts of judging not as independent and detached, but as an interrelated system, within which every assertion entitles us to other assertions (which must be carefully deduced since they constitute its meaning) and to which we are entitled only through other assertions (so that they must be carefully searched for). 'Scientific' as used in this article thus means the possibility of establishing an order of judgments such that each one when made is of use in determining other judgments, thereby securing control of their formation."[205] This view of science as an order of judgments requires a special treatment of the generic ideas, the 'conclusions,' or universals of science. The individual judgment, 'This, _A_, is _B_,' expresses an identity. But it is much better expressed in hypothetical form. "Identification, in other words, is secure only when it can be made through (1) breaking up the analyzed. This of naive judgment into determinate traits, (2) breaking up the predicate into a similar combination of elements, and (3) establishing uniform connection between some of the elements in the subject and some in the predicate."[206] Identity exists amid relevant differences, and the more intimately the system of differents is understood, the more positive is the determination of identity. This will be recognized as the 'concrete universal' of the Hegelian logicians.
