To a man of science, a theory is something to be tested. He seeks not to defend his beliefs, but to improve them. He is, above everything else, an expert at changing his mind. The fellow who considers the whole world a problem might be surprised to hear what the world thinks of him. Be careful not to tangle with the fella who thinks before he acts.
People see, hear, and believe only what they want to see, hear, and believe.
A well is not an ocean. Strive to substantiate your facts from several sources. Those who do not, handle excuses. I liked that. I liked that too.
