It has been generally supposed that certain self-ascriptions, such as “I am in pain”, are infallible. This seems right. However, it is clear enough that the self-ascriptive thought is not identical to the state ascribed: the pain isn’t the same as the thought about it. This means that these are “distinct existences”, in the Humean sense. But if they are distinct existences, they can be conceived apart, which implies that they are contingently connected. So there must be worlds in which the ascription occurs without the state ascribed–which would make the ascription false. So the ascription is fallible. How then can we maintain infallibility while accepting that distinct existences are contingently connected? This is the puzzle of infallibility. How can the metaphysics (distinct existences) be made to fit with the epistemology (infallibility)?
Is something valuable because we value it or do we recognize value in something that it has independently of being valued? (Compare: is something good because the gods say it’s good or is goodness something that the gods in their wisdom recognize?) One way to answer this question is to ask if there can be mistakes of value–this suggesting that value is logically independent of valuing. Consider a tribe that eats both carrots and broccoli. Both nourish them and taste equally good. They have value. However, the religion of the tribe decrees (for no good reason) that carrots are the godlier vegetable and dedicates a good deal of reverence and ritual to the act of carrot eating. They regard carrots as of far more value than broccoli. Aren’t they simply wrong about this? Carrots and broccoli have equal value, in fact (“objectively”), but they are mistaken about this; they have been misled by their religious ideology. (Compare the value placed on chastity in our religious tradition.) Thus, value is not determined by valuing.
