Note 1 — IX.

The last few sentences seem like a paragraph from some psychologist of the day. My colleague, Professor W.B. Pillsbury, for example, has just published a book on the attention, in which appears the following statement: "It seems that the problem of voluntary activity is largely, if not entirely, a problem of the attention ... . The processes which are effective in the control of a man's ideas are ipso facto in the control of his movements," and this, besides being the current psychology, is quite in accord with our doubter's vision: "Well thought is well done." (See Attention, chapter ix. London, 1907.)
