Most of what we know we don't really know first hand. I've never seen a cancer cell. But I trust this community of experts who have, so I believe that cancer exists. But we trust these experts, and we trust that the experts have a system of checks and balances and self-correction. And we have to insist that experts have certain certifications. They're not perfect. Every once in awhile there's an engine falls off the wing of a plane, or a tax audit happens and you find out your expert made a mistake. But it's a pretty good system. It's the best system we've got.
Although it is easier to find information these days, it is easier than ever before to find misinformation, pseudo-facts, unsupported and fringe opinions, and the like. Children should be taught at an early age what constitutes evidence, how to detect biases or distortions in newspaper accounts, and that there exist hierarchies of information sources. In the medical field, for example, a controlled experiment published in a peer-reviewed journal is a better source than a blog by the Ginseng Growers Association, promoting the health benefits of their own product.
Paul Davies takes us on a logically and rhetorically compelling modern search for human agency. This outstanding analysis, well informed by naturalistic views of our evolved affective nature, is the kind of philosophical work that is essential for a field to move forward when ever-increasing findings from modern science are inconsistent with traditional philosophical arguments. This book is for all who wish to immerse themselves in the modern search for free will. It is steeped in the rich liqueur of current scientific and philosophical perspectives and delusions.
The emerging picture from such studies is that ten thousand hours of practice is required to achieve the level of mastery associated with being a world-class expert - in anything. In study after study, of composers, basketball players, fiction writers, ice skaters, concert pianists, chess players, master criminals, and what have you, this number comes up again and again…no one has yet found a case in which true world-class expertise was accomplished in less time. It seems that it takes the brain this long to assimilate all that it needs to know to achieve true mastery.
Our ignorance of the cosmos is too vast to commit to atheism, and yet we know too much to commit to a particular religion. A third position, agnosticism, is often an uninteresting stance in which a person simply questions whether his traditional religious story (say, a man with a beard on a cloud) is true or not true. But with Possibilianism I’m hoping to define a new position - one that emphasizes the exploration of new, unconsidered possibilities. Possibilianism is comfortable holding multiple ideas in mind; it is not interested in committing to any particular story.
If you cannot always elicit a straight answer from the unconscious brain, how can you access its knowledge? Sometimes the trick is merely to probe what your gut is telling you. So the next time a friend laments that she cannot decide between two options, tell her the easiest way to solve her problem: flip a coin. She should specify which option belongs to heads and which to tails, and then let the coin fly. The important part is to assess her gut feeling after the coin lands. If she feels a subtle sense of relief at being "told" what to do by the coin, that's the right choice for her.
If an epileptic seizure is focused in a particular sweet spot in the temporal lobe, a person won´t have motor seizures, but instead something more subtle. The effect is something like a cognitive seizure, marked by changes of personality, hyperreligiosity (an obsession with religion and feelings of religious certainity), hypergraphia (extensive writing on a subject, usually about religion), the false sense of an external presence, and, often, the hearing voices that are attributed to a god. Some fraction of history´s prophets, martyrs, and leaders appear to have had temporal lobe epilepsy.
We are nothing but the product of billions of years of molecules coming together and ratcheting up through natural selection, we are composed only of highways of fluids and chemicals sliding along roadways within billions of dancing cells, trillions of synaptic conversations hum in parallel, this vast egglike fabric of micron-thin circuitry runs algorithms undreamt of in modern science, and these neural programs give rise to our decision making, loves, desires, fears, and aspirations. That understanding would be a numinous experience, better than anything ever proposed in anyone's holy text.
People are trying to build a society where they can talk across the aisle so to speak, and have civil discourse. At the same time we're trying to inform ourselves about what's really true so that we can make evidence based decisions that is better than superstition or rumor. But the fact is that people who use evidence based decision making have much better life outcomes, greater life satisfaction, they live longer, they make better personal and medical decisions, better financial decisions. But parallel to that is you can't reason somebody out of a position they didn't reason themselves into.
