In fact, among all the mutations that have affected the knowledge of things and their order, the knowledge of identities, differences, characters, equivalences, words - in short, in the midst of all the episodes of that profound history of the Same - only one, that which began a century and a half ago and is now perhaps drawing to a close, has made it possible for the figure of man to appear. ... If those arrangements were to disappear as they appeared, if some event of which we can at the moment do no more than sense the possibility - without knowing either what its form will be or what it promises - were to cause them to crumble, as the ground of Classical thought did, at the end of the eighteenth century, then one can certainly wager that man would be erased, like a face drawn in sand at the edge of the sea.
