Philosophical Background Matters
This chapter discusses the rift between science and philosophy, but argues that scientists can benefit from philosophical insights without becoming philosophers. It presents an elementary introduction to philosophical concepts that recur throughout the book, including deduction, induction, inference, and others. It covers the problem of induction and the Uniformity of Nature assumption, and reviews Hume’s critique of induction. Other technical issues that confuse the public debate about science, concern explanation, uncertainty, and levels of organization of science, are in here as well. A central issue is the question of how we can resolve two opposing notions: the widely agreed on principle that scientific findings are never completely certain, and our conviction that some findings are certain: e.g., the earth goes around the sun in an elliptical orbit. The chapter sorts out this and other common misunderstandings.
