The Law of Identity (A is A) is a rational man’s paramount consideration in the
process of determining his interests. He knows that the contradictory is the
impossible, that a contradiction cannot be achieved in reality and that the
attempt to achieve it can lead only to disaster and destruction. Therefore, he
does not permit himself to hold contradictory values, to pursue contradictory
goals, or to imagine that the pursuit of a contradiction can ever be to his
interest.
