We saw in the beginning that the exigences of bodily life gave consciousness its first articulation. A bodily feat, like nutrition or reproduction, is celebrated by a festival in the mind, and consciousness is a sort of ritual solemnising by prayer, jubilation, or mourning, the chief episodes in the body’s fortunes. The organs, by their structure, select the impressions possible to them from the divers influences abroad in the world, all of which, if animal organisms had learned to feed upon them, might plausibly have offered a basis for sensation. Every instinct or habitual impulse further selects from the passing bodily affections those that are pertinent to its own operation and which consequently adhere to it and modify its reactive machinery. Prevalent and notable sensations are therefore signs, presumably marking the presence of objects important for the body’s welfare or for the execution of its predestined offices. So that not only are the soul’s aims transcripts of the body’s tendencies, but all ideas are grafted upon the interplay of these tendencies with environing forces. Early images hover about primary wants as highest conceptions do about ultimate achievements. [Sidenote: Its worthlessness as a cause and value as an expression] Thought is essentially practical in the sense that but for thought no motion would be an action, no change a progress; but thought is in no way instrumental or servile; it is an experience realised, not a force to be used. That same spontaneity in nature which has suggested a good must be trusted to fulfil it. If we look fairly at the actual resources of our minds we perceive that we are as little informed concerning the means and processes of action as concerning the reason why our motives move us. To execute the simplest intention we must rely on fate: our own acts are mysteries to us. Do I know how I open my eyes or how I walk down stairs? Is it the supervising wisdom of consciousness that guides me in these acts? Is it the mind that controls the bewildered body and points out the way to physical habits uncertain of their affinities? Or is it not much rather automatic inward machinery that executes the marvellous work, while the mind catches here and there some glimpse of the operation, now with delight and adhesion, now with impotent rebellion? When impulses work themselves out unimpeded we say we act; when they are thwarted we say we are acted upon; but in neither case do we in the least understand the natural history of what is occurring. The mind at best vaguely forecasts the result of action: a schematic verbal sense of the end to be accomplished possibly hovers in consciousness while the act is being performed; but this premonition is itself the sense of a process already present and betrays the tendency at work; it can obviously give no aid or direction to the unknown mechanical process that produced it and that must realise its own prophecy, if that prophecy is to be realised at all.
