4. The discussion of the time-element in judgment leads up to the next puzzle--that as to the way in which one judgment can be marked off from another in the total activity of thought. Bosanquet has pointed out that subject and predicate are both of them present at every stage of the judging process, and are undergoing progressive modification. If, therefore, we take a cross-section of the process at any point, we find both subject and predicate present; but a cross-section at one point would not reveal quite the same subject and predicate as the cross-section at another point. He comes to the conclusion that judgment breaks up into judgments as rhomboidal spar into rhomboids (p. 88). It is, accordingly, quite arbitrary to mark out any limits for a single judgment. The illustration he gives of the point is as follows: Take such an every-day judgment of mixed perception and inference as, "He is coming down stairs and going into the street." It is the merest chance whether I break up the process thus, into two judgments as united by a mere conjunction, or, knowing the man's habits, say, when I hear him half way down stairs, "He is going out." In the latter case I summarize a more various set of observations and inferences in a single judgment; but the judgment is as truly single as each of the two which were before separated by a conjunction; for each of them was also a summary of a set of perceptions, which might, had I chosen, have been subdivided into distinct propositions expressing separate judgments; _e. g._, "He has opened his door, and is going toward the staircase, and is half way down, and is in the passage," etc. If I simply say, "He is going out," I am not a whit the less conscious that I judge all these different relations, but I then include them all in a single systematic content "going out." (P. 89.)
