Law of identity

Definition and stakes

Cora May Williams A Review of the Systems of Ethics Founded on the Theory of Evolution

The law of Identity expresses, therefore, not entire sameness, with which the cessation of all thought would be reached, but simple consistency. It affords us, thus, the means of recognizing the Untrue in that which is not what it is called, hence also the means of recognizing the True. The law of Excluded Middle contains an extension or doubling of the law of Identity, in that the identity here appears, not in the form of consistency, but in that of contradiction

Claude Fayette Bragdon The Beautiful Necessity

Now every principle of natural beauty is but the presentment of some occult law, some theosophical truth; and this law of Diversity in Monotony is the presentment of the truth that identity does not exclude difference. The law is binding, yet the will is free: all men are brothers united by the ties of brotherhood, yet each is unique, a free agent, and never so free as when most bound by the Good Law.
