Lee Smolin, The Trouble with Physics, NY, 2007, pg 297
Science was not invented. It evolved over time, as people discovered tools and habits that worked to bring the physical world within the sphere of our understanding. Science, then, is the way it is because of the way nature is - and because of the way we are.
id, pg 298
We happen to live in a world hospitable to our understanding
ibid, pg 299
[W]e are masters at drawing conclusions from incomplete information.(...) We never have enough information to completely justify the conclusions we draw. Being able to act on guesses and hunches, and act confidently when the information we have points somewhere but does not constitute a proof (...) is a big part of what makes human beings such a succesful species.
But this ability comes at a heavy price, which is that we easily fool ourselves.
ibid, pg 299
[C]ontroversy is essential for the progress of science.(...) [W]hen we are forced to reach a consensus by the evidence, we should do so. But (...) until the evidence forces consensus, we should encourage a wide diversity of viewpoints.
ibid, pg 304
The one thing that everybody who cares about fundamental physics seems to agree on is that new ideas are needed. (...)
How do we find that missing idea? Clearly, someone has to either recognize a wrong assumption we have all been making or ask a new question
