PHLA10H3 Lecture Notes - Lecture 9: Rationality, Philosophical Skepticism
Document Summary
Epistemology: part of philosophy that tries to evaluate the commonsense idea that we have knowledge and that we are rationally justified in the beliefs we have. Philosophical skepticism: claiming that we don"t have knowledge, or that our beliefs aren"t rationally justified. Three kinds of knowledge: know how: knowledge of how to do something. Example: s knows how to ride a bicycle: object knowledge (know who): knowledge of a person, place, or thing. Example: s knows the president of the united states: propositional knowledge (know that): knowledge if a proposition is either true or false. Example: s knows that the rocky mountains are in north america. Knowledge requires two necessary conditions: an objective (truth) and subjective (belief) side. They aren"t sufficient: a fact is objective if its truth doesn"t depend on the way anyone"s mind is. Truth: knowing whether something is true or not.
