I think philosophy is a worthy pursuit for a scientist. It's easy to get a feeling of going somewhere with science, because someone else has done a lot of thinking for you making you comfortable with your result. But if you leave philosophy more confused than when you started, you won't have the mental fortitude to make real progress in science. I think philosophy is ultimately the study of human thought. It's why courses on logic are an important component of undergraduate studies in philosophy. Having a good understanding of human thought, how we come to the decisions we make and how we fool ourselves with lazy thought, is invaluable in making deep scientific discoveries. When you don't come away more confused, but with a deeper understanding, you are better prepared to understand the why, instead of just accepting the how. You would know why science works, instead of making snarky remarks about science and that it works.

If you really think about it, the situation in science, that the questions that were hard to answer were still unsolved, is very similar to the situation in philosophy. Ask anyone what an electric field really is. No one knows.
