Whittaker, following Siebeck, pointed out the important role Plotinus assigns to the functions of imagination in psychic life. Imagination is the terminus ad quern of all properly human conscious experience; it is that faculty of man without which there can be no conscious experience. The sensitive soul is an imaginative soul below which there is Nature, or vegetative soul, which acts without being conscious. When the functions of reason are added to sensation to produce a rational human being, there is (...) conscious discursive thought as well as conscious sensation; and since the sensitive soul cannot be responsible for the imaging of rational concepts, Plotinus asserts the existence of a conceptual imagination.

Professor P. Bernays has kindly drawn my attention to the fact that the assignment of Godel numbers to formulas described on page 295 of volume I of this Journal, is not correct. Under this assignment, different formulas may obtain the same Godel number and therefore the argument given on page 296 under (i) is not cogent. The correct assignment would give, for the formula considered as an example, the Godel number 28. 320. 514. 782 The correction to be made on (...) page 294, L 20 is obvious. (shrink)

Professor P. Bernays has kindly drawn my attention to the tact that the assignment of Gödel numbers to formulas described on page 295 of volume I of this Journal, is not correct. Under this assignment, different formulas may obtain the same Gödel number and therefore the argument given on page 296 under (i) is not cogent. The correct assignment would give, for the formula considered as an example, the Gödel number 23. 329. 514. 732 The correction to be made on (...) page 294, l. 20 is obvious. (shrink)
