The fetishistic illusions enveloping all phenomena of capitalist society succeed in concealing reality, but more is concealed than the historical, i.e. transitory, ephemeral nature of phenomena. This concealment is made possible by the fact that in capitalist society man's environment, and especially the categories of economics, appear to him immediately and necessarily in forms of objectivity which conceal the fact that they are the categories of the relations of men with each other. Instead they appear as things and the relations of things with each other (p.14).A nice little primer for his seminal essay on alienation and reification that appears later in the same book, if you ask me.
Also reminder time. This weekend sees the Carnival of Socialism swing by this blog. If you want something included let me know either via comments or my email, which you can find in my profile.
