Document Summary

Pain" is a nonrigid designator conceptually equivalent to a definite description of the form. According to lewis what my pains and the robot"s pains share is a causal role, not anything physical; there is no physical similarity between human and martian pain that makes them pain. Two issues 1. how to state functional theory in a detailed way and 2. what type of states could possibly realize the relational propositional attitude states. The upshot of the famous "twin earth" arguments has been that meaning and content are in part in the world and in the language community. Functionalism dictates that mental properties are second order properties, properties that consist in having other properties that have certain relations to one another. Lack of knowledge can have serious, even fatal, consequences. 1. propositional knowledge or knowledge-that - factual i. e. the earth is round. 2. acquaintance knowledge, or personal knowledge being familiar with something. Attempting to break knowledge apart truth, belief, justification.
