Well, Dawkins has no philosophical that I have ever been able to discern. Copleston's history is outstanding. There ought to be something by Gabriel Marcel. And I would have included William Luijpen's Existential Phenomenology.
Somewhat ill-digested: asking a lot of people for one book or series is going to produce that effect. I guess that the Coppleston makes sense, as giving one a synoptic view.
