Identity

[I]f you want to make a perfect duplicate of something, all you need to do is to put identical parts in identical structure. The principle is the metaphysical underpinning of industrial mass production; to make another ’01 Ford Explorer, all you need to do is to assemble identical parts in identical structural configurations.

I pretended to be somebody I wanted to be, and I finally became that person.

Cary Grant, quoted in 'Notes on Fashion' John Duka, Notes on Fashion, The New York Times, 1981, pp. 16, p. 16

A proper body’s not an object, not an implement, not a belonging to be admired, it’s just you, yourself. Only when it’s no longer you, but yours, a thing owned, do you worry about it –Is it in good shape? Will it do? Will it last?
