"If we are forced to choose between being rationally correct but emotionally uncomfortable, and irrationally incorrect but emotionally comfortable, we frequently choose to be irrational." - Raymond Ruble, Critical Thinking, 48.
When I consider the beauty and design of the world and the conscious, moral, creative, loving human existence, it does not seem reasonable to me to conclude that matter is all that is and that we have evolved to this point. Instead, there is evidence throughout history of supernatural longing and experience. Without an obvious physically observable explanation of our existence, it is logical to suggest that there is something else, some spiritual source.
"If a book be false in its facts, disprove them;if false in its reasoning, refute it. But for God's sake, let us freely hear both sides if we choose."
- Thomas Jefferson
"To be rational is so glorious a thing that two-legged creatures generally content themselves with the title." - John Locke
