Peer reviewedKelly, I.W. – Psychology: A Quarterly Journal of Human Behavior, 1980
Examines Jean Piaget's theories on the laws of formal logic, and Johnson's claim that the law of noncontradiction is only descriptive of macroscopic objectives. Suggests Piaget and Johnson are wrong, since the possibility of saying anything significant and informative presupposes the law of noncontradiction is followed. (Author)
