I have found that reason can kill irrationality. But is it always such? I don't necessarily believe irrational can be defined for everyone, though it is at the same time concrete. The word means an idea, notion, or principle thought with no basis of evidence or reasoned logic. Well, I say the idea of religious intolerance, or homophobia, or racism are irrational. No evidence supports these ideas save cultural bias. But then, cultural bias is an evidence in itself. Your religion might not support homosexuality. But then, is your religion rational? Find me concrete, non-circumstantial evidence of your God's existence, and it would not be irrational. Until then, all religious views are irrational. So, all moral principles which can't be proven, are therefore both rational and irrational. There is evidence, but the evidence is irrational. To truly be rational, the idea must have no opinion, bias, interpretation, or any real existence outside of the realm of science. Gravity is inarguable, and is the force which governs our universe. Gravity is not an opinion, it is a scientific law, and a property of physics. Physics is the rule book for our universe, and all the universe obeys the laws of physics. Physics, and all items therein, are rational. Philosophy, unfounded emotions, religion, and mysticism are all irrational factors of human life, and I intend to rid myself of them. Opinions should be based on natural facts, and facts alone, with no irrational basis. Anything irrational is a poison to society, and we can see this by looking at how religion has destroyed the world piece by piece, and only the guiding hands of atheists and secular humanists have moved us forward in any constructive way. In fact, the only useful thing religion has ever done was create the calendar, but if we're being honest with ourselves, agrarians would have done it eventually, for the purpose of tracking harvests and seasonal development periods. So I am left with science and the questions it raises. I firmly believe that if we are to prosper, we must embrace science, and all other fields of rational inquiry the way most of us embrace the unfounded idea of a God. If there is a God, he would be proven to exist by science, not church, so in the scope of things, we should all be scientists, not preachers and students. So I embrace rational thought over doctrine, discovery over worship, and most of all, prosperity over oppression. You all should, too.
