 By what standard are we to think our efforts “to be,” our manner of being a self? If such standards traditionally derive from the essence that a particular thing instantiates—this hammer is a good one if it instantiates what a hammer is supposed to be—and if there is nothing that a human being is, by its essence, supposed to be, can the meaning of existence at all be thought? Existentialism arises with the collapse of the idea that philosophy can provide substantive norms for existing, ones that specify particular ways of life. Nevertheless, there remains the distinction between what I do “as” myself and as “anyone,” so in this sense existing is something at which I can succeed or fail. Authenticity—in German, Eigentlichkeit—names that attitude in which I engage in my projects as my own (eigen).
