I had no idea that rationalism was such a force here considering that we spend so much of our time deliberating on the beauty of a curve and how we feel about groups of them.
Well, the techniques by which we create those curves depend on reason. Reason and emotion go hand in hand. It's what I like about type design.
There was a study a few years ago that looked at people who had damage to the part of their brain that generates emotions. They appeared to be normal, but had no emotions. And they were unable to make decisions.
Mysticism is not a way to know about the world except by accident, although its existence tells a lot about how the human brain works.
Human beings are not perfectly rational creatures. Perfect knowledge is not necessary for survival. Our brains our subject to illusions, just like our senses, but it is more difficult to detect because our brain is the thing we use for detecting things. Our desires, emotions, and existing beliefs play into this as well. Hence, we easily and naturally adopt unsupportable beliefs about the world. In other words, mysticism.
The scientific method is a workaround we discovered that enables us overcome our cognitive shortcomings. Science allows us to transcend mysticism, not the other way around.
