Hi everybody my name is Vince. I'm a 25 year old guy with tons of ideas, opinions, and crass speculations concerning psychology, particularly cognitive and evolutionary aspects of it that I'm not qualified to have, as I've no degree or any sort of formal training in the subject. I come by these largely through spending way too much time on the Internet and not nearly enough chasing girls so that one day my mom can have grandkids from both her children. Honestly, the woman won't leave me alone! I hope people here will take my attempts at discussion in the spirit of open and honest dialogue. I'll start off with a brief sketch on but one of the topics on which I have an unqualified opinion.
I believe that religion is evolutionary in nature, that it is an adaptation humans have evolved in order to deal with uncertainty. Uncertainty itself is, what I believe to separate us from the animals, only humans are capable of conceiving of broad, abstract ideas concerning the nature of the realities they live in. In all other respects our cognition is the same as other animals in regards to kind, if not in degree. These broad, abstract realities allow us to make certain higher order predictions, such as analyzing the behavior of other animals like bees, or possible predators. We can abstract an entire world of another person or animal inside our head, and use that model to make predictions. That is what I believe to be the true separator of us from other apes. From this we've created culture, which is an attempt to communicate in the language of these different models.
However, if our brains were allowed to run amok with this sort of distracting activity, we would leave ourselves vulnerable to attacks from other animals or men. So we evolved religion in order to help safeguard us from our own minds. The religion offered us something that our brains would never conjure up on our own, answers. Answers to existential questions that would plague a primitive mind without the benefit of modern schools of philosophy such as ethics. Without some kind of answer to the question, "what is it all for?" we would never have been able to function properly in a dangerous environment, and would have fallen victim to constant warring amongst individuals in tribes. Existential angst often mentally cripples people today, it must have been incredibly harsh on a man whose only social circle involved 30 or so others and is ruled by the threat of violence. So religion gave us a way to trick ourselves into focusing on the present instead of the concept of broader meaning.
Religion today provides us with the same balm. It provides meaning to people, allowing them to focus on the present, giving them a reason to do what evolution wants them to do. Religion is but a higher evolution of instinct. Instinct evolved in order to allow an animal to function, it takes away the choice of how to react in certain situations. Humans still have instincts, of course, but they've largely been subsumed by religion.
What does this tell us, personally? That religion, while it cannot be used to describe reality or the universe, has a place in the proper functioning of a human being. Studies show that people who believe in religion are happier on average. People just function better when they believe in a higher power.
What does this mean for atheists? Unfortunately, this means that we will always be in the minority. Religion evolved to solve a basic problem with the way our brains work. Only a similarly-scaled functionality evolution of the brain would eliminate the need for an uncertainty-obviating mechanism.
It does mean that we are right. There is no God, no spirit, and nothing that could be explained outside the natural laws. If the entirety of religion can be boiled down to evolution, Occam's Razor demands that we discard entities regarding metaphysical explanations. It could be proven by finding the genes for religion. If we could turn them off and produce atheists consistently, that would be the final nail in the coffin. Naturally, that won't be the end of theism, because we'd have to turn all the genes on everybody off to do that. People will still believe, even in the face of overwhelming evidence to the contrary. They're programmed to.
It also means that religion isn't evil. So many of the atheists I meet are hostile towards religion. I don't understand the attitude myself. It's the way people function. Why rail so hard against a basic fact of human nature? Atheists are going to have to learn how to get along with theists, and accept the fact that they will forever be the minority and that they will continue to never get any respect for their refusal to just shut up and believe.
Some might argue, "Well, if it's genetics, it should be heritable, right? Plenty of atheists come from religious parents, and it looks to be squarely on the side of nurture, not nature." While I'm sure there are slight differences in the expressions of the religiosity genes, I believe that everybody, including atheists, contains the genetic code. Plenty of atheists recant later, particularly on their deathbeds. Atheism may be related to a "rebelliousness" genetic expression. The rebelliousness of youth might itself have genetic origin, a topic for another discussion. I've heard plenty of atheists that have experiences which a religious person would call religious in nature. The atheists just use different language to describe those experiences. Also it's probable that the genetic code doesn't distinguish between atheism and theism, and affects both in exactly the way it was intended to function. It just so happens that atheists use different words to describe their faith. Faith in this case being the genetic imperative to disregard existential questions, disallowing the angst that it engenders from infecting their minds.
