This is a particular problem for me, because my own entry into philosophy (entirely fortuitous, as anyone's), rather than just knowing about the history of philosophy, is Levinas. I believe it is completely impossible (though some think you can, and maybe even he did at one stage of his work) to separate his philosophical from his religious writings. When I had given this up, I thought about it negatively and naively, and their inseparability meant that he was susceptible to the same Nietzschean critique as Kant, but now I think that I am entirely wrong about that, because it puts the meaning of God in Levinas in completely the wrong place conceptually and historically.
