Abstract
Doing of some sort, undeniably, may have a connection of some kind with knowing in some sense. Take the slogan, "learning by doing." It points to the fact that one can acquire knowledge of how to do something--in the sense, at any rate, of acquiring the ability to do it--in the course of the doing. But, if undeniable, this fact seems also trifling. Nor would it mean much more to say that one can acquire such knowledge or ability only by the doing, though this is probably true if we grant that actions can be performed in the imagination.
