Now consider a case in which we do take up an observant attitude towards a voluntary action, I mean the very instructive case of trying to draw a square with its diagonals by placing a mirror on your drawing paper and directing your hand by what you see by looking at it in the mirror. And here one is inclined to say that our real actions, the ones to which volition immediately applies // for which volition is immediately responsible // , are not the movements of our hand but something further back, say, the actions of our muscles. We are inclined to compare the case with this: Imagine we had a series of levers before us, through which, by a hidden mechanism, we could direct a pencil drawing on a sheet of paper. We might then be in doubt which levers to pull in order to get the desired movement of the pencil; and we could say that we deliberately pulled this particular lever, although we didn't deliberately produce the wrong result that we thereby produced. But this comparison, though it easily suggests itself, is very misleading. For in the case of the levers which we saw before us, there was such a thing as deciding which one we were going to pull before pulling it. But does our volition, as it were, play on a keyboard of muscles, choosing which one it was going to use next? ‒ ‒ For some actions which we call deliberate it is characteristic that we, in some sense, “know what we are going to do” before we do it. In this sense we say that we know what object we are going to point to, and what we might call “the act of knowing” might consist in looking at the object before we point to it or in describing its position by words or

pictures. Now we could describe our drawing the square through the mirror by saying that our acts were deliberate as far as their motor aspect is concerned but not as far as their visual aspect is concerned. This

, e.g., be demonstrated by our ability to repeat a movement of the hand which had produced a wrong result, on being told to do so. But it would obviously be absurd to say that this motor character of voluntary motion consisted in our knowing beforehand what we were going to do, as though we had had a picture of the kinaesthetic sensation before our mind and decided to bring about this sensation. Remember the experiment ◇◇◇ (?) p. 62; if here, instead of pointing from a distance to the finger which you order the subject to move, you touch that finger, the subject will always move it without the slightest difficulty. And here it is tempting to say, “Of course I can move [o|i]t now, because now I know which finger it is I'm asked to move.” This makes it appear as though I had now shown you which muscle to contract in order to bring about the desired result. The word “of course” makes it appear as though by touching your finger I had given you an item of information telling you what to do. (As though normally when you tell a man to move such-and-such a finger he could follow your order because he knew how to bring the movement about.)
