Peterson is interesting to read (I will get downvoted for this) is anything he says particularly radical and world changing no. It’s a good and more importantly modern and current and there’s a lot of supplementary material to go and look at if you so desire.

I definitely don’t agree with everything he said but that’s the point of reading it. You read it to question your own beliefs and make sure that they are indeed your beliefs.

There’s all the obvious classical philosophers and ‘older’ philosophers but a lot of that content is important to view in the context of the time frame.

One person who I don’t see mentioned a lot is Thomas Sowell but he’s less philosophy more economic based so if that’s interesting to you then I’d recommend.
