non-Aristotelian logic

a coined phrase from non- meaning "not" or "negation" and Aristotelian, of or having any relation to Aristotle (384322 B.C.), Greek philosopher. For nearly 2000 years after Aristotle many used his philosophy and doctrines in their own thinking. But to the scientific revolution of the sixteenth and seventeenth centuries, Aristotelianism was considered the straitjacket that kept learning in confinement. During that time, an attack was launched on the tradition of Aristotelian logic which supplied alternative materials on the subject of logic and continued into the mid-1900s.
