Most of my life I've been very, very unintestered in philosphy but I've recently developped a curiosity for some philosophical concepts like "structuralism" and I'm a bit curious about what the fuck type of political philosphy the Greeks developped after a friend told me they were reading Aristotle for their poli-sci class. What should I read? No self-help books please and thank you.
I would suggest reading Existential Comics and their description (start with the Marxist ones if you can click on persons). Honestly 80% of philosophy stuff is having a feel for who and when some stereotypes about philosophers, philosophy and such are thrown around.
About the Greeks: they had some interesting stuff and are in Eurozentric academic education the foundation of philosophy and as such held in high regards. Though they have concepts like "philosopher kings" and it is good that there is an elite that rules over the people and slaves. A lot of what is academic held in high regard is stuff that ruling elites found helpful. So remember that at any point there were multitudes of philosophies that were marginalized, ignored or purged.
Philosophy is also found in real movements and by real authors (those today not seldomly include intersectionality and or the stories of marginalized). Different to Kant who was a racist that did the same walk every lunch and had people taking care of preparing his lunches. Consequently his philosophy has no problem with racist stuff, like the rule of one race over the other (cause they are civilized and have to force the others to become enlightened).
In a sense when you talk about real problems with your friends and concepts it is philosophy in a more real sense than what liberals or austrian marxket libertarians do. Marx's wrote in his 11th thesis about Feuerbach: "The philosophers of the world only interpreted the world differently, the point, however, is to change it".
Enjoy your intellectual travel, learning is good.
Existential Comic's " How to learn philosophy as an amateur " is good
