“They say ‘doubt everything,’ but I disagree. Doubt is useful in small amounts, but too much of it leads to apathy and confusion. No, don’t doubt everything. QUESTION everything. That’s the real trick. Doubt is just a lack of certainty. If you doubt everything, you’ll doubt evolution, science, faith, morality, even reality itself — and you’ll end up with nothing, because doubt doesn’t give anything back. But questions have answers, you see. If you question everything, you’ll find that a lot of what we believe is untrue… but you might also discover some things ARE true. You might discover what your own beliefs are. And then you’ll question them again, and again, eliminating flaws, discovering lies, until you get as close to the truth as you can.
