The qualifying of pure feeling to attain actions suitably differentiated for distinct forces must have proceeded very slowly, and have had the dimmest beginning. We cannot suppose that consciousness attained at once and easily to a manifold of sense, much less have had this brought to it, involuntarily received. The earliest forms of sensations were no doubt of those affections of the body produced by heat, pressure, and other elements which determine most vitally the existence of the organism. The first sensation indeed was undoubtedly not in any particular mode, but was a bare and undifferentiated form. It was some such indefinite and general sensation as we may sometimes detect near the vanishing-point of consciousness just before pure pain state occurs. For example, the sense of heat as such is lost at a given temperature for a given case, and there exists for a moment a vague general sensation, sensation _per se_, before mere pain absorbs all consciousness. Sensation at its very origin was not sense of any kind, sense of heat, pressure, etc., but a mere undifferentiated sense of bodily affection. The body is not, of course, apprehended as object, but there is a vague attributing and qualifying which marks the state as more than purely central, as being a real objectifying. Toothache, for instance, implies ache before the toothache, and this general aching is the type of early unorganized sensation. Pain is the essence of the state, and is throughout dominant, the cognition in mere aching being a very minor element. “I was awakened in the night by a toothache,” is the objective description of a triple movement in consciousness, pain, ache, toothache. The earliest cognitive experiences were all of this very general type of sensation, which becomes gradually more definitely localized and qualified as distinct modes of sensation; pain-hunger, pain-heat, pain-pressure, and corresponding pleasure-sensations are differentiated. Subtract the mere pain from hunger state and from painful sensation of heat, and we have certain _quales_ which are difficult to analyse, but which are cognitive in nature. Diverse bodily affections are _sensed_ diversely instead of being _felt_ in one mode, pure feeling.
