Why is philosophy science of all science?

The philosophy of science is

concerned with the assumptions,

foundations, methods and implications of science.

It is also concerned with the use and merit of science and

sometimes overlaps metaphysics and epistemology by exploring

whether scientific results are actually a study of truth.

In addition to these central problems of science as a whole,

many philosophers of science also consider problems that apply

to particular sciences (e.g. philosophy of Biology or philosophy of physics).

Some philosophers of science also use contemporary results in science to reach conclusions about philosophy.

Philosophy of science has historically been met with mixed response

from the scientific community. Though scientists often contribute to the field,

many prominent scientists have felt that the practical effect on their work is limited;

a popular quote attributed to physicist Richard Feynman goes,

"Philosophy of science is about as useful to scientists as ornithology is to birds."

In response, some philosophers (e.g. Jonathan Schaffer) have

pointed out that it is likely that ornithological knowledge

would be of great benefit to birds, were it possible for them to possess it. :D xx
