Hegel's revision of Aristotle

Hegel's revision of Aristotle

Aristotle laid down the  3 basic principles of logic:

1. the principle of identity(A=A)

2. the principle of noncontradiction [Not (A and not A)]

3. The principle of the excluded middle [either (A) or (not A)]

 

Hegel believed these principles to be erroneous.

so, in his dialectic, everything is in some sense its opposite;

1. A = not A

therfore, 2. the principles of noncontradiction and 3. of the excluded middle collapse too.
