Note 435 — Chapter XIII
Reading edition
Mind, xi, 377 ff. He says: "I apparently either distinguished the impression and made the motion simultaneously, or if I tried to avoid this by waiting until I had formed a distinct impression before I began to make the motion, I added to the simple reaction, not only a perception, but a volition."—Which remark may well confirm our doubts as to the strict psychologic worth of any of these measurements.
