I can talk about Greek philosophy. I'm just not a fan of most of it. After Pythagoras, Plato, and Aristotle, most philosophy (Greek and otherwise) became a quest for the ultimate expression of ideals, symmetry, etc.. Western philosophy operates on the assumption that this is an ordered universe, and the philosopher's quest is to figure it all out. I'm a fan of the Greek philosopher Heraclitus, whose writings no longer exist, but who famously said "No one ever steps in the same river twice". This is a paradigm rarely expressed in Western philosophy. He dispenses with an ordered universe right away. Eastern philosophy is closer to him. We're only now embracing some of the same ideas with quantum physics.
Anyways, this is a roundabout way of saying that the tenets underlying a lot of philosophy appeal to NTs by default, who already think in terms of big picture patterns and global systems. If philosophy had taken Heraclitus' route, and we had more schools of thought coming from him, you'd probably see more ISTPs who'd discuss it. You see some very philosophical STPs in the East - Taoism and certain branches of Buddhism teach the same kind of fluidity. Look at Bruce Lee. "Be like water." It just depends on what you define as "philosophy" first.
