I can't remember when it was, this Lent or last Lent, when philosopher of religion that I am facebook friends with (whose identity I will not reveal, as the post wasn't public) wrote (paraphrasing): "I'd like us to pray for our profession during this period, especially with all the ugly things that have come to light." I found this striking (and a beautiful intention too) and it sheds some light how, for this person, philosophy and personal beliefs interrelate.
I am currently in the process of writing up a paper on a qualitative survey I conducted with philosophers of religion, which indicates how one's metaphysical outlook can affect one's philosophical work. Discussions on how faith or lack of faith might influence one's philosophical work aren't new. The PhilPaper survey revealed strong correlations between theism and philosophy of religion as an area of specialization, and theism and a number of other views, such as libertarian free will. However, there is another way in which religion and philosophy interact. Not only does one's religious belief - or lack thereof - influence one's work in philosophy of religion and other areas of philosophy. One's work as a philosopher also has an influence on how we like to conduct and present ourselves as persons in the world. This is not only the case for Christian philosophers, but for philosophers more generally.
Michael Rea, in a forthcoming paper, provides the following sobering observations:
One of the most important job skills of an analytic philosopher is strongly correlated with whatever skill is involved in successfully rationalizing bad behavior, deceiving oneself, putting a positive spin on bad circumstances, and so on. Also, there are certain modes of behavior—ways of being ambitious, or arrogant, or disrespectful to others, for example—that seem much easier to fall into in professions (like philosophy) where reputation, and having oneʼs own reputation elevated over the reputations of people with whom one works, is often correlated with promotions, job security, pay raises, and the like.
