Abstract

Self-knowledge occupies a central place in the thought of the Socratics. As he makes it the characteristic feature of the figure of Socrates and of his search for the good life, Plato develops in his own right Socrates’ views on self-knowledge in a variety of ways, all of which incorporate the intuition that proper awareness of ourselves is determined, at least partly, by factors external to the individual. The aim of the pre­sent paper is to substantiate precisely this claim.The first part outlines an interpretation of certain features of the Apology, where Plato appears convinced that full knowledge of oneself involves ele­ments of objectivity. The second and the third sections are devoted, respecti­vely, to the Charmides and to the first Alcibiades, both of which imply that the individual needs to turn away from himself and towards objective facts and values in order to acquire complete understanding of his own self. The fourth part applies that conclu­sion to a puzzle raised by the metaphor of the Cave in the seventh book of the Republic and proposes a tentative solution to that puzzle. The last part compares Plato’s account to that of another group of Socratics, the Cyrenaics, who hold that self-knowledge is achieved introspec­tively through inner sense. The paper ends with a few remarks concerning the importance of self-knowledge for morality and the pertinence of Plato’s account to contemporary ethics and philosophy of mind.
