ABSTRACT
In this chapter I shall offer an interpretation of the meta-ethical—and more broadly, meta-evaluative—ideas developed or adumbrated in Sartre’s early philosophical works, in the period from the late 1930s to the Notebooks for an Ethics, written between 1945 and 1948. While ethical concerns were expressly excluded from his early magnum opus, Being and Nothingness (cf. Sartre 2003: 434, 647), they take center stage in his immediate post-war writings, especially in the Notebooks and, famously, in his 1945 lecture Existentialism and Humanism, but they are also present in the earlier War Diaries.
