Hilary Putnam (1981) proposed an interesting and much discussed attempt to refute a skeptical argument that is based on one form of the brain-in-a-vat scenario. In turn, Putnam’s attempted refutation is based on content externalism (also known as semantic externalism). On this view, the referents and meanings of various types of singular and general terms, as well as the propositions expressed by sentences containing such terms, are determined by aspects of the speaker’s external environment. In this entry, we will consider (...) the basic features of and problems with Putnam’s original argument, and we will also present and discuss several of the most important attempts to reconstruct or improve upon that argument.

Gary Ebbs has argued that skepticism regarding knowledge of the contents of one's own mental states cannot even be coherently formulated. This articles is a reply to that argument.

There is a continuing debate as to whether externalism about mental content is compatible with certain commonly accepted views about the nature of self-knowledge. Both sides to this debate seem to agree that externalism is _not compatible with the traditional view that self-knowledge is acquired by means of observation. In this paper, I argue that externalism is compatible with this traditional view of self-knowledge, and that, in fact, we have good reason to believe that the self-knowledge at issue is acquired (...) by means of observation.

RÉSUMÉ: Dans un article récent, Victoria McGeer a proposé une conception de la connaissance de soi, qui se présente comme une alternative au modèle du rapporteurprédicteur selon lequel confesser des croyances consiste à rapporter des «états sousjacents» de soi-même. McGeer met l’accent, à la place, sur une approche actantielle: la connaissance de soi, selon elle, est engendrée par les actions responsables que l’agent entreprend pour rendre vrais ses propres aveux quant à ses croyances. Le présent article est une discussion critique (...) de cette conception de McGeer. Une première objection a rapport à l’explication du comportement, et une seconde concerne la tentative du modèle actantiel pour rendre compte du caractère d’autorité de la connaissance de soi.
