How do we know what we know? Philosophy tells us that knowledge can be inherent, deductive reasoning, or it can be based on experience. What it cannot be is just imagination or personal prejudice. Science, which looks for knowable facts, depends upon something being at least 3 things: observable, repeatable, and testable. Everything else is either personal preference or something we should be more suspicious of than gas station sushi!
