Utilitarianism, Capitalism, History

As has been previously discussed, the Empiricist concepts of Pleasure and Pain are a-temporal.  Accordingly, the positive and negative modifications of them in the standard versions of the Utilitarian Calculus express neither increase nor decrease, but, rather, merely differences in degrees of intensity with respect to non-feeling.  In contrast, Spinoza's concepts of the two, represent an increase and a decrease, respectively, in strength, and, hence, are inherently temporal, as are, analogously, Economic Profit and Loss.  So, if the ambition of Bentham and Mill is to model Ethics on Capitalism, Utilitarianism should adopt Spinoza's concepts, on the basis of which the 'greatest happiness of the greatest number' would be the temporally accumulated, optimally coordinated, strengths of the members of a society.  On such a model, History would be revealed as an essential dimension of both Utilitarianism and Capitalism.
