Could anybody recommend some good ancient philosophical and or Archivable readings?

I have not read in a while but some of the authors in which i like to read will be listed and i would appreciate if you didnt list these authors or verses(being as im already aware of their writings) would be Confucius, Sun Tzu((not philosopy)although im only aware of the ''Art of War'') and Niccolo Machiavelli.

plato's charmedes is very good. you can find it in a number of plato collection books. he speaks fluently on the actual act of philosophizing, and to top it off, i think it was only like 20 pages. quick and good read.
for some more in depth plato, there's plato's the republic. if you read this, you should also read machiavelli's republic as well. you can see alot of paralells between the two, although machiavelli along with a number of other renissance writers focused alot on era politic, which makes for some dryer reading with the key philosophical points hidden behind the application of them.
enjoy.

Immanuel Kant on Deontology

Karl Popper is the greatest philosopher of the 20st century, he writes about about all other philosophers as well (and why and where they went wrong).
Karl Popper invented the concept of falsifiability, and thus he defined the meaning of "scientific" and made it possible to easily spot imposters, post-modernists, dogmatsts, theologians and other intellectual frauds and sellouts.

If you are interested in this kind of stuff, check out http://thesciencenetwork.org. It has many contemporary scientists of all fields speaking on Video.

I especially liked the bolded, but if you're really looking to get into Philosophy, I really suggest reading Plato first.

aristotle--ethics

Can many of these titles generally be bought at a local book store, say, Barnes and Noble?
