1. (P=P)v(P=/-P)
2. (Pv-P)=(Pv-P)
3. (P=/-P) = (P=/-P)
A. The principle of excluded middle and non contradiction require the law of identity in order to have identities.
B. The Principle of Identity and Non contradiction are subject to the principle of excluded middle.
C. Considering the Principle of identity is needed for the Principle of identity and non contradiction, in an either or dichotomy non contradiction is negated.
D. Non contradiction is subject to the Law of Identity thus the law of identity is negated, while the negation of the law of non contradiction allows the law of identity to progress to P=-P.
E. If P=-P then PV-P is negated, however (P=P)v(P=/-P) is logically sound as identity is not non contradiction thus an either or approach is necessary.
Etc.
