Philosophy literally means "love of knowledge". It came to be in the way that we understand it through the greeks. It is the premise that one can arrive at truth through the process of thinking. Rationality and logic would be the operative principle informing this search. It is particularly valuable for those who do not believe in god because I see philosophy as the inevitable counterpart to religion.
