Perception AND Reason

I know we have been comparing perception and reason, and trying to choose which one is better, but I can't honestly make that decision. They are both so important in gaining true knowledge and I don't think you can seperate them and still learn much. Not only do you need those two, but you need language and emotion as well, because all of them need to work together to fix each others' flaws. As we said in class, your perceptions can deceive you and need your reason to decide what is real and what isn't. For example, the optical illusion(in my other post) with the lines that appear crooked, but are really straight, you need your reason to decide what they are, as your perception is telling you they are crooked. However, you can do other visual tests to figure out if they are straight, which I guess is only using your perception and not your reason. All in all, I think you need all four ways to gain true knowledge because they all work together to detect false information.
