Lately I've been putting a lot of thought in to what is rational and what must be relegated to faith alone. Ever since the scientific method was discovered, humanity has attempted to put it to work in so many areas. After all, discoveries exploded once we were set free from the shackles of tradition.
The problem is, Scientific Method, to be true to itself, must be testable. It does not lend itself to the study of morality or philosophy, for instance, because how do we test if a hypothesis is true? How do we judge in the end what is "good" and what is "bad"?
Words alone just don't do the trick. Words can be tangled and misinterpreted. Words can trip us up. When I want to express a process clearly to my audience, I draw a process map. So that's what I've done. Here's a "mind map", rather simplified, to describe how a person using reason comes to a decision.
