Reason provides the structure or form of what we know, the senses provide the content. Perhaps there is nothing about knowledge that is ultimate, but rather a web of interlocking beliefs. Justification is thus a social, historical phenomenon. Abnormal discourse lacks such criteria. Periods of social change are characterized by struggles between normal and abnormal discourse.
Truth is thus a property of a statement.
The facts exist independently of our knowledge of them. Accurate observations can report actual states of affairs and cannot result in reasonable disagreement. This changes the notion of truth away from a property of a statement to the reasons we provide for beliefs. We cannot know the world apart from our knowledge. That is, the consequences of being able to integrate knowledge, predict events, achieve goals determine whether a belief is true.
