This paper analyzes the very important notion of capital from a Marxian perspective as opposed to a neoclassical one. It is argued that when capital is viewed as a historically determined social process (relation), rather than as a thing or a col-lection of things, it tends to assume certain specific forms more often than others depending on the particular stage of economic history. Capital thus refers simulta-neously to social relations and to things. Given this frame of reference, notions such as money and property capital are more easily accommodated and conse-quently are not written off as financial or fictitious capital - not real capital because they produce nothing. The paper also focuses on Marx’s important analy-sis of the time of production and the turnover of capital in terms of the production of surplus-value (profit). It then examines Marx’s equally important and prescient analysis of how the turnover speed of capital is affected by the time of circulation of commodities (the realization of surplus-value) and the growing use of credit (in its various forms) in the capitalist system. Finally, the paper turns its attention to the economic role of time as it relates to interest - bearing capital - one whose clear comprehension rests on viewing capital as a social construct.
