Our volitional habits depend, then, first, on what the stock of ideas is which we have; and, second, on the habitual coupling of the several ideas with action or inaction respectively. How is it when an alternative is presented to you for choice, and you are uncertain what you ought to do? You first hesitate, and then you deliberate. And in what does your deliberation consist? It consists in trying to apperceive the ease successively by a number of different ideas, which seem to fit it more or less, until at last you hit on one which seems to fit it exactly. If that be an idea which is a customary forerunner of action in you, which enters into one of your maxims of positive behavior, your hesitation ceases, and you act immediately. If, on the other hand, it be an idea which carries inaction as its habitual result, if it ally itself with prohibition, then you unhesitatingly refrain. The problem is, you see, to find the right idea or conception for the case. This search for the right conception may take days or weeks.
I spoke as if the action were easy when the conception once is found. Often it is so, but it may be otherwise; and, when it is otherwise, we find ourselves at the very centre of a moral situation, into which I should now like you to look with me a little nearer.
The proper conception, the true head of classification, may be hard to attain; or it may be one with which we have contracted no settled habits of action. Or, again, the action to which it would prompt may be dangerous and difficult; or else inaction may appear deadly cold and negative when our impulsive feeling is hot. In either of these latter cases it is hard to hold the right idea steadily enough before the attention to let it exert its adequate effects. Whether it be stimulative or inhibitive, it is too reasonable for us; and the more instinctive passional propensity then tends to extrude it from our consideration. We shy away from the thought of it. It twinkles and goes out the moment it appears in the margin of our consciousness; and we need a resolute effort of voluntary attention to drag it into the focus of the field, and to keep it there long enough for its associative and motor effects to be exerted. Every one knows only too well how the mind flinches from looking at considerations hostile to the reigning mood of feeling.
Once brought, however, in this way to the centre of the field of consciousness, and held there, the reasonable idea will exert these effects inevitably; for the laws of connection between our consciousness and our nervous system provide for the action then taking place. Our moral effort, properly so called, terminates in our holding fast to the appropriate idea.
If, then, you are asked, “In what does a moral act consist when reduced to its simplest and most elementary form?” you can make only one reply. You can say that it consists in the effort of attention by which we hold fast to an idea which but for that effort of attention would be driven out of the mind by the other psychological tendencies that are there. To think, in short, is the secret of will, just as it is the secret of memory.
