The Meaning of Science: An Introduction to the Philosophy of Science

Science has produced causes for every thing from the mechanisms of insect navigation to the formation of black holes and the workings of black markets. yet how a lot do we belief technological know-how, and will we really understand the area via it? How does technology paintings and the way does it fail? and the way can the paintings of scientists help—or hurt—everyday humans? those are usually not questions that technological know-how can solution by itself. this is often the place philosophy of technology is available in. learning technological know-how with no philosophy is, to cite Einstein, to be “like a person who has obvious hundreds of thousands of timber yet hasn't ever noticeable a forest.” Cambridge thinker Tim Lewens indicates us the wooded area. He walks us during the theories of seminal philosophers of technology Karl Popper and Thomas Kuhn and considers what technological know-how is, how some distance it could possibly and may achieve, and the way we will ensure the character of its truths and myths.

those philosophical matters have results that reach some distance past the laboratory. for example: What position may still scientists have in coverage discussions on environmental matters resembling fracking? What are the biases at play within the look for a organic functionality of the feminine orgasm? If mind scans can be utilized to illustrate selection used to be made a number of seconds sooner than anyone truly makes a wide awake selection, what does that let us know in regards to the threat of loose will?

via studying technology via this philosophical lens, Lewens unearths what physics can train us approximately truth, what biology teaches us approximately human nature, and what cognitive technology teaches us approximately human freedom. A masterful research of the largest clinical and moral problems with our age, The that means of Science forces us to confront the sensible, own, and political reasons of science—and why it concerns to all of us.
