Why I am a 'Possibilian' - David Eagleman

This is why I am big fan of Eagleman and his theories ozzing with limits of our human knowledge in an universe where knowledge is limitless - here:

"Good science is always open-minded, and the history of science is one of surprises and overturnings. Science is nothing but careful thinking, and careful thinking encourages an appreciation of the complexity of the world. The complexity encourages us to maintain several possibilities at once. In a single lifetime, we may have no way to remove the ambiguities from these possibilities.

A scientist may tend to favour one story over the others, but will always be careful to concede uncertainty and maintain a willingness to change the balance with new, incoming information. As an example, there are two very different interpretations about the reality underlying quantum physics. It is possible that there will be no way to ever know which is correct, or if instead some entirely new theory is correct. And that ambiguity is accepted as part of the enormity of the mysteries we face, and the terms of the agreement we have with nature.

So while there are plenty of good books by scientist-atheists, they sometimes under-emphasise the main lesson from science: that our knowledge is vastly outstripped by our ignorance. For me, a life in science prompts awe and exploration over dogmatism.

Given these considerations, I do not call myself an atheist. I don't feel that I have enough data to firmly rule out other interesting possibilities. On the other hand, I do not subscribe to any religion. Traditional religious stories can be beautiful and often crystallise hard-won wisdom - but it is hardly a challenge to poke holes in them. Religious structures are built by humans and brim with all manner of strange human claims - they often reflect cults of personality, xenophobia or mental illness. The holy books of these religions were written millennia ago by people who never had the opportunity to know about DNA, other galaxies, information theory, electricity, the big bang, the big crunch, or even other cultures, literatures or landscapes.

So it seems we know too little to commit to strict atheism, and too much to commit to any religion. Given this, I am often surprised by the number of people who seem to possess total certainty about their position. I know a lot of atheists who seethe at the idea of religion, and religious followers who seethe at the idea of atheism - but neither group is bothering with more interesting ideas. They make their impassioned arguments as though the God versus no-God dichotomy were enough for a modern discussion.

This is why I call myself a "possibilian". Possibilianism emphasises the active exploration of new, unconsidered notions. A possibilian is comfortable holding multiple ideas in mind and is not driven by the idea of fighting for a single, particular story. The key emphasis of possibilianism is to shine a flashlight around the possibility space. It is a plea not simply for open-mindedness, but for an active exploration of new ideas."
