On the essence of identity............

 But when meaning has been disciplined out of language, and the pride of doing something better than other people banished, and the superficial clarity of being a man or a woman prohibited, and the practical instinct of protection and of self-protection disallowed, and life’s simple practices shamed out of existence—when all these timeless human things, all created out of the senses, melt into air, then nothing in our experience will remind us of anything else in our experience, and we will lose the ability to discriminate, to cherish, to judge. Instead of continually expanding our sympathies by helping us to follow the thread of truth through dissimilarity, the moral imagination will shrink to nothing. And then any comparison, and any equivalence, is possible.
