the crowds arent wise and the aristocrats are bound to be corrupt with soo much power.

im looking for something that would give me perspective into cyncism, epicurneism, stocism and other ethical philosophies. I already have a good understanding of cyncism, epicurneism and stocism but i want to know more about the other ethical philosophies.

Is there any textbook or general book on ethics concerning primarily this question?

Can people just reccomend some books?
