Please read Marx's "Manuscript of Economy Philosophy (Gyeong-Je-Hak-Cheol-Hak-Soo-Go)". Usually the interpretative writings of Marx's original works are apt to mislead readers (partly due to cold war). Even though the Marx's work is difficult for a novice to understand, there is an old and good phrase, "if you read one hundred times, you can understand it (Dok-Seo-Baek-Pyeon-Yi-Eui-Ja-Hyeon)". Furthermore, Marx is a very good materialist, so he always try to say about the present situation, i.e., the Capitalist Society, on the contrary to the Christian who always says about God which cannot be felt (you are very lucky if you feel God!!!). Anyway, it's important for you to have your own opinion on great thinkers.
