What is the value of philosophy of science? What do philosophers even know about science? Shouldn't we just trust scientists when it comes to questions of science? Philosopher Subrena Smith says there are presuppositions in science worth analyzing from a philosophical perspective.

Does science progress in a cumulative way?  In other words, do later scientific theories build upon earlier ones by keeping older established truths about the world, and adding us more truths?  The standard answer, familiar from Whiggish history and brief historical asides in scientific textbooks, is that it does.
