In the epistemological discussion posted yesterday, there are some truths that arise that I wanted to post today as a side note:
As discussed yesterday, we know that rational knowledge exists before experience. Assuming that someone with no experience could exist, we still could not say that they had no knowledge. The possession of knowledge necessarily implies that the person has existence. Therefore, it cannot be said that just because an individual does not or has not yet experienced the world that the he is not a person, does not exist, or is not alive.
These truths are monumental when you consider abortion. It is with certainty that we can know that if a fetus reacts to his environment, then he is alive, because to react you must be able to perceive, and to perceive implies empirical experience.
