Karl Marx is one of the most influential and controversial thinkers
of modern times. Though receiving some terrible PR from the (misguided) attempts
to implement Marx's ideas, his philosophy is not only powerful and inspiring
but also relevant to our times. Marx is typically portrayed as an economic
thinker but he is actually a thinker of time, history and nature of human
progress and his ideas touch on the very essence of human nature. His ideas
about communism were not something to be implemented but rather something that
has to eventually happen since history orders so. Marx's analysis of the way
society function on the role terms such as class conflict, ideology and alienation
within it are still relevant when we come to understand contemporary societies
(largely due to the fact that capitalism, despite Marx's prophecy, is also
still contemporary).
Marx's theory and ideas are extended and elaborated. Here are a few
summaries to help you understand some of his most important texts, such as The
