Sameness across history is knowable only through what is new.

Evidence

The identity lies in the non-identity, in what, not having yet come to pass, denounces what has. The statement that things are always the same is false in its immediateness, and true only when introduced into the dynamics of totality. He who relinquishes awareness of the growth of horror not merely succumbs to cold-hearted contemplation, but fails to perceive, together with the specific difference between the newest and that preceding it, the true identity of the whole, of terror without end. — Theodor W. Adorno, Minima Moralia, 256
