What is science, and how does it work? Are scientists in the business of discovering objective truths? Many think that is obvious, but others argue science can only produce models with predictive and explanatory power, not truths. Are there really such things as laws of nature and cause and effect? What, at an essential level, do we mean when we talk about scientific methods and scientific explanations? Philosophy of science addresses these questions directly, by taking a step back and exploring what can be taken for granted in the practice of science.
The first half of this course focuses on how to distinguish science from pseudoscience, which turns out to be an unexpectedly challenging task, by drawing upon the ideas of major figures (Popper, Kuhn, Lakatos, Feyerabend, and Duhem, amongst others). The second half of the course examines debates in contemporary philosophy of science. Must science always explain? Is observation ever theory-neutral? Do scientists confirm or falsify theories based on evidence alone, or do values play a role? Can science ever be value-free and, if not, what does this say about the objectivity and rationality of scientific knowledge? Is science ultimately socially constructed?
This course provides students with the tools of logic, conceptual analysis, rigorous argument to reflect more deeply on the fundamental nature of science.
