Arguments For PC
Phenomenal Conservatism has been defended on three grounds.
- First, the principle enables one to account for the justification of most, perhaps all, of the beliefs that we commonly take as justified, including sensory observations, memory beliefs, and beliefs based on reasoning.
- Second, it is argued that alternative epistemological positions are self-defeating in the sense that, unless PC is true, few or no beliefs would be justified, including beliefs in any alternative epistemological theories. This is supported by the claims
- that all or nearly all beliefs are causally explained by appearances, that is, one believes a proposition because it seems true to one; and
- that a belief is justified only if it is causally explained by a factor that constitutes justification for the proposition believed.
- Third, it is argued that PC is most faithful to the motivations underlying epistemological internalism.

Famous quotes containing the words arguments for and/or arguments:
“Compared to football, baseball is almost an Oriental game, minimizing individual stardom, requiring a wide range of aggressive and defensive skills, and filled with long periods of inaction and irresolution. It has no time limitations. Football, on the other hand, has immediate goals, resolution on every single play, and a lot of violence—itself a highlight. It has clearly distinguishable hierarchies: heroes and drones.”
—Jerry Mander, U.S. advertising executive, author. Four Arguments for the Elimination of Television, ch. 15, Morrow (1978)
“Argument is conclusive ... but ... it does not remove doubt, so that the mind may rest in the sure knowledge of the truth, unless it finds it by the method of experiment.... For if any man who never saw fire proved by satisfactory arguments that fire burns ... his hearer’s mind would never be satisfied, nor would he avoid the fire until he put his hand in it ... that he might learn by experiment what argument taught.”
—Roger Bacon (c. 1214–1294)
