Any scientist motivated by the quest of knowledge (as opposed to just a career, as often happens) has a little philosopher inside him. He may not be conscious about it though.
This is nonsense.
There is a big difference between scientific knowledge and philosophical knowledge. To say that science is based on philosophy is like saying that literature is based on calligraphy... there is a historical connection, but the ends are quite different. Science is based on things that are measurable, testable and repeatable. Philosophy is based on cultural ideas, things that seem true and feel right.
There is a place for philosophy, there are questions that can't be answered by the exacting standards of scientific inquiry. But philosophy has absolutely nothing to do with science.
People who start any serious study of science do mathematical problem sets, they seek for precise tools to measure, quantify and test. People who study Philosophy study history... they read the ideas of Philosophers before.
I have studied science, and I have taken courses in Philosophy. There is almost nothing in common in content or in practice.
