Ueberweg maintains that the subject of the impersonal is the actual totality of present experience. When we ask, "What rains?" we must understand a reference to our general environment, in which no special element is singled out. Sigwart, on the other hand, maintains that the subject can be construed only as the actual sense-impression. This diversity of opinion might seem to indicate that, were it not for the constraining power of theory, a subject would scarcely be thought of for the impersonal. Still it must be admitted that when we examine the impersonal expression closely we can discover a sense-impression, whether definite or indefinite, combined with an idea. This would seem to give the case to the orthodox logician, for he will at once claim the sense-impression as the subject and the idea as the predicate of the judgment. But we must have a care. Predication is usually held to consist in a _reference_ of predicate _to_ subject. The factors of the judgment are, as it were, held apart. In the impersonal no such thing as this can be discovered. The meaning is so close a unity that impression and idea are entirely fused. We may analyze the expression and find them there, but by so doing we destroy the immediacy which is an essential characteristic of the impersonal. In other words, the impersonal does not analyze itself. It is entirely unconscious of its make-up. And yet it is definite and applies itself with precision: If I am in a lecture-hall and hear the fire-alarm, the thought "Fire!" which enters my mind leads to an immediate change in my conduct. I arise, move quietly out, and prepare for duty. If, on the other hand, I open the street door and the rain strikes my face, I ejaculate "Raining!" turn, reach for my umbrella, and pass out protected. In both cases I act _knowingly_ and with _meaning_, but I do not analyze the movement either of thought or of action. A correlate to the unreflective impersonal judgment is found in early custom. Custom embodies social ideas and is an instrument for the determination and control of action. Individuals moved by custom know what they are about and act with precision according as custom may demand. But it is notorious that custom is direct and unreflective. It represents social instruments of control which have grown up without method and which represent the slow accretion of rule-of-thumb activities through many ages. So in the impersonal judgment we have a type of intellectual instrument which has been brought to a high degree of precision in use, but which still retains the simplicity and certainty of an unquestioned instrument of action. For this reason, whatever complexity of elements the impersonal may present to a reflective view, it does not contain to itself. Consequently it may be best to say that to the impersonal there is neither subject, predicate, nor reference of the one to the other. These are distinctions which arise only when the instrument of action has been questioned and the mind turns back upon the meaning which it has unhesitatingly used, analyzing, investigating, constructing, laying bare the method and function of its tools. Thus arises a new and distinctive type of judgment, viz., the reflective.
