Plucked this line from Harvey's review of Piketty, not having finished reading even that yet: “Money, land, real estate and plant and equipment that are not being used productively are not capital.”
Not having started Marx's, and not having plans for Piketty's, I am fascinated by capital in the overlap of its economic and philosophic capacities - as I'm sure many, if not all, of you are.
Maybe thirdform can help out here, or john.
Can we figure capital as the head of a growing stock? Something that only is as long as the stock is growing? Thus, removing your stock from any kind of circulation/reproduction would be, as it were, decapitating your stock, and issuing in a plateau-unto-decline. Once the head of an ale diminishes, the flattening commences (alongside its consumption).
So yeah, all capital is surplus stock, but not all surplus stock is capital?
How can we generalize, then, capitalism (as a set of beliefs/practices surrounding a reproductive use of stock) from its economic context? In what other manners can one be a capitalist?
As anathema as it is in my eyes, I do sense a profound capitalism in the way I go about learning. If there is not a perpetual increase/exercise of skills-of-abstraction, a sense of insufficiency sets in - the head dissipates.
