Dare to think!
The truth is incontrovertible. Malice may attack it, ignorance may deride it, but in the end, there it is.

I believe in the discipline of mastering the best that other people have ever figured out. I don’t believe in just sitting down and trying to dream it all up yourself. Nobody’s that smart.
