In the earliest stage of mind, as has been before noticed, all manner of material causes rouse nought more than a pure feeling mode; heat, pressure, electricity, sound, light, nutriment or its absence, if they attain to waken the function of consciousness, accomplish no more than pure feeling as bare pain and pleasure. It is, of course, natural to conceive that from the first consciousness, responds objectively in sensation in as many modes as organism is moved by external and internal forces; but a multiform sense origin of consciousness is not borne out by the general tendency and law of evolution, nor yet by such special indications in consciousness as we are able to observe. When a very young infant seems to reach pleasurably to warmth, if we are correct in positing consciousness at all, it is still very unlikely that there is sense of warmth, but the state is probably pure pleasure; and if there is sense of warmth, it did not give the pleasure, but the reverse. We believe likewise that it is probable that a consciousness response to nutriment is, at first, mere pleasure, and only, secondarily, organic sensation. Thus, warmth and nutriment effect, but only, at first, in the one mode of pure feeling, and secondly, pure sensation as general organic satisfaction. Lastly arises a differencing in consciousness for the different bodily changes. And the multiformity of stimulus and paucity of consciousness in modes while so very apparent in early mind is yet always found in all grades of psychic life. The responsiveness of consciousness is never perfected, and mind has a practically infinite field for the acquirement of sensation, for appreciating what has never affected consciousness, or which mind has felt or known only by some general mode. The infant, no doubt, has many pains for which it has no sensation values. These pains, perfectly pure and undifferentiated the one from the other, have had their occasion in a variety of physical changes. A native of the tropics, who on first touching ice says it burns, has at first but a single sensation for very diverse physical affections; but he soon attains an icy sensation, that ice feels not burning, but stinging cold. Men, civilized and educated, often are consciously affected by bodily changes of which they are wholly incognizant, the psychosis being not specialized according to the mode of change. In degraded states of consciousness, which come to all, there often appears obscure feeling and sensation, which is a practically single mode of answer to a very wide variety of physical excitation. In realizing the variety of external objects and changes the mind proceeds but slowly, each new form always at first in pure feeling. It is only as something affects feeling and interest that we ever come to know it or its manifestations in physiological change.
