How deep are you willing to let the razor cut?
I'm not sure what you mean. But if you mean what I think you mean then:
The deeper I cut the more sure I am of what I think about the subject when I ultimately have evidence to support it.
I know that it hurts when the razor cuts, it's when I start throwing away any unnecessary claims about the world that I would
like to have, it's when I have to face the fact that I'm wrong about some things. But in the end, as I have learned in life, it's pays off to do the right thing (rationally) despite personal conviction. I can look people in the eye, it's honesty.
