What is Philosophy of Science?


Back to course document list.

What is Philosophy of Science?

"The field of philosophy of science encompasses the philosophical scrutiny of science, both in general and in its particular branches; and the scientific scrutiny of those issues in philosophy to which the content of scientific theories and their methods are relevant."

Mission statement, Center for Philosophy of Science, University of Pittsburgh

This definition identifies two parts to philosophy of science. In one, the methods of philosophical analysis are applied to an understanding of science itself. These methods have no mysterious content or powers. They amount to an insistence on the clear statement of ideas and claims and that they be supported by cogent arguments. That one should proceed in this way is widely accepted. What distinguishes professional philosophers is that, even when the problems are tough and the going very murky, they will not compromise on clarity and cogency and still find ways of proceeding.

The second part of the definition reflects the fact that philosophy is not a closed field. Its traditional problems--the nature of space, time and matter; life; mind; experience; and so on--can overlap with the concerns of the sciences. Indeed one should expect that a knowledge of these sciences has something of use for the traditional problems.

These two parts roughly align with another division in philosophy of science. On one side we have the treatment of issues common to all sciences, so-called "general philosophy of science." Its concerns include the structure of theories, the nature of experiment, induction and confirmation, explanation, scientific realism and scientific change. On the other side we have the analysis of problems peculiar to individual sciences. It includes "philosophy of physics," "philosophy of biology," "philosophy of cognitive science" and so on.

What is Good Philosophy of Science?

Good philosophy of science is done this way:

   Formulate and state clearly an interesting and novel thesis and argue cogently for it.

This recipe is easy to state as an abstract conception. We can point to many excellent examples of it. We each have our own favorites. I am a great fan of Carl ("Peter") Hempel and Wesley ("Wes") Salmon. They were masters of the craft. Their writing is lucid. Their logic is precise. They make it look easy. Consult any of their works and make emulating them your goal.

There are, unfortunately, many ways that we can be distracted from writing good philosophy of science:

    Mere science writing.
    Proposing new science.
    Purely historical studies.
    Excesses of mathematical precision.
    Pointless axiomatization.
    Naming of parts.
    Merely suggestive questioning.
    Reductions to the more problematic.

These traps are elaborated individually in my Goodies page: How Not to Do Philosophy of Science: A Guide for Makers and Consumers.
