'For a New Liberty' by Murray Rothbard along with 'Healing Our World in an Age of Aggression' by Mary Ruwart are the two books that finally got me seriously looking into and considering anarcho-capitalism (which i eventually embraced in its entirety) in contrast to my minarchism and Stockholm syndrome to the state at the time.
But otherwise, all the sources mentioned in this thread are great recommendations!
Also, welcome to the forums eugenekop and I see you are seriously thinking about the spectrum of libertarian philosophy and contrasting it to your modern day liberalism. Good luck!
If you value justice, self-ownership, and logical consistency, you'll certainly find a new home with libertarian philosophy :-D
Plus you'll be able to squash your liberal buddies with undefeatable and brutally consistent logic, economics, ethics/morality - and you'll be able to easily expose them for the hypocrites they ultimately are ;-)
