Despite the vast number of religions, nearly everyone in the world believes in the same things: the existence of a soul, an afterlife, miracles, and the divine creation of the universe. Recently psychologists doing research on the minds of infants have discovered two related facts that may account for this phenomenon. One: human beings come into the world with a predisposition to believe in supernatural phenomena. And two: this predisposition is an incidental by-product of cognitive functioning gone awry. Which leads to the question ...Is God an Accident ?
we see people as separate from their bodies, we easily understand situations in which people's bodies are radically changed while their personhood stays intact. Kafka envisioned a man transformed into a gigantic insect; Homer described the plight of men transformed into pigs;But it is just as likely that this idea comes up in stories so often because it is surprising to us - like the baby surprised when an object doesn't fall - rather than a reflection of how we see ourselves.
But the real problem with natural selection is that it makes no intuitive sense. It is like quantum physics; we may intellectually grasp it, but it will never feel right to us.I addressed the idea of intuition about scientific principles in a recent AskMe question here (I have linked to that too often, but it fits perfectly here...), the point being that there is nothing particularly counter intuitive about quantum physics, or any other theory. The reason the baby is amazed when gravity doesn't work is that the baby expects gravity to work. If you learn to expect quantum mechanics to work in a certain way and the rules suddenly change, you will be amazed too. Or to put it another way - because so many of you expect quantum mechanics to be amazing - flight amazes us less and less every generation because it is becoming part of learned intuition.
This is not a value judgment. Many of the good things in life are, from an evolutionary perspective, accidents. People sometimes give money, time, and even blood to help unknown strangers in faraway countries whom they will never see. From the perspective of one's genes this is disastrous�the suicidal squandering of resources for no benefit.It is my understanding that this is an open question, and that there is ongoing study trying to understand altruism in an evolutionary context. That makes this a statement about the author's personal philosophy, not science.

Doubt is itself an action within a cognitive framework. One believes in a certain standard that defines what constitutes evidence; what constitutes sound reasoning..etc. So, if I doubt 'something', I'm saying that I believe in a certain (maybe unelaborated) framework within which I can't accept 'something'. I believe the contents of this very post, based on my expectation of what is sound reasoning.Sure. This cognitive framework we call 'science'. When I doubt a proposition I am finding it insufficiently supported to add my personal scientific body of knowledge.

As indicated above, QM is widely thought to be a strongly non-deterministic theory. Popular belief (even among most physicists) holds that phenomena such as radioactive decay, photon emission and absorption, and many others are such that only a probabilistic description of them can be given. The theory does not say what happens in a given case, but only says what the probabilities of various results are. So, for example, according to QM the fullest description possible of a radium atom (or a chunk of radium, for that matter), does not suffice to determine when a given atom will decay, nor how many atoms in the chunk will have decayed at any given time. The theory gives only the probabilities for a decay (or a number of decays) to happen within a given span of time. Einstein and others perhaps thought that this was a defect of the theory that should eventually be removed, by a supplemental hidden variable theory[6] that restores determinism; but subsequent work showed that no such hidden variables account could exist. At the microscopic level the world is ultimately mysterious and chancy.Read more from the article.
So goes the story; but like much popular wisdom, it is partly mistaken and/or misleading. Ironically, quantum mechanics is one of the best prospects for a genuinely deterministic theory in modern times! Even more than in the case of GTR and the hole argument, everything hinges on what interpretational and philosophical decisions one adopts. The fundamental law at the heart of non-relativistic QM is the Schrödinger equation. The evolution of a wavefunction describing a physical system under this equation is normally taken to be perfectly deterministic.[7] If one adopts an interpretation of QM according to which that's it -- i.e., nothing ever interrupts Schrödinger evolution, and the wavefunctions governed by the equation tell the complete physical story -- then quantum mechanics is a perfectly deterministic theory. There are several interpretations that physicists and philosophers have given of QM which go this way. (See the entry on quantum mechanics.)
For any quantum experiment we merely take as the relevant Bohmian system the combined system that includes the system upon which the experiment is performed as well as all the measuring instruments and other devices used in performing the experiment (together with all other systems with which these have significant interaction over the course of the experiment). The "hidden variables" model is then obtained by regarding the initial configuration of this big system as random in the usual quantum mechanical way, with distribution given by |ψ|2. The initial configuration is then transformed, via the guiding equation for the big system, into the final configuration at the conclusion of the experiment. It then follows that this final configuration of the big system, including in particular the orientation of instrument pointers, will also be distributed in the quantum mechanical way, so that this deterministic Bohmian model yields the usual quantum predictions for the results of the experiment.So the theory says that you can take a random initial condition, evolve it through a deterministic system, and end up with a random result.
"We had many conversations about science and history, just like in the old days. But now he had something new to talk about, his children. He said: "I always thought I would be a specially good father because I wouldn't try to push my kids into any particular direction. I wouldn't try to turn them into scientists or intellectuals if they didn't want it. I would be just as happy with them if they decided to be truck-drivers or guitar-players. In fact I would even like it better if they went out in the world and did something real instead of being professors like me. But they always find a way to hit back at you. My boy Carl for instance. There he is in his second year at MIT, and all he wants to do with his life is to be a god-damned philosopher!"
