I recently listened to your latest episode and was somewhat surprised to hear you describe 5's view's on slavery as Aristotelian. While I can see why one might argue that, since Aristotle does talk about natural slaves, I thought it would be a better fit to describe 5's anthropology, and probably his morality, as Nietzschean. However, I think this is interestingly contrasted by his existential questioning, which I think would best be described as Kierkegaardian. I think Five is at the point in his existential thought that Kierkegaard would describe as needing to take the "leap of faith". Five can't seem to do this, however, and I think this is portrayed in his rejection of the humanities and his retreat into the sciences, the idea that, if he just looks hard enough, he can bootstrap himself out of his problem by his own sheer force of will. This would be where his Kierkegaardian leanings end and his Nietzschean tenancies begin.
