One reservation I have about many famous philosophers is that the majority of them were men, and a significant subset of those men were sexist because those were the times they lived in.
So for example Aristotle is probably my #1 influence in terms of philosophy, but the guy was kind of a tool with regards to his thoughts about women. He viewed us as inferior. So I have to kind of politely ignore that aspect of his character when I'm talking about how good some of his writings were.
So when I say I'd like to meet him as one of my top three, it's kind of with the understanding that if he were in today's world, his views on the sexes would change.
That's a problem with most people from older times in general. Like, some of the U.S. founding fathers were polymaths, but also had sympathies with slavery or owned slaves, and didn't give women the right to vote.
Many people in history have had genius level intellect and yet in today's world have some unspeakably stupid views on some matters of race, sex, religion, etc.
(beyond the fact of no one believing me those are the original Jesus, Diogenes and Gautama Buddha of course
