41 " [O]ur percept is an elaborate computer model in the brain, constructed on the basis of information coming from [the environment], but transformed in the head into a form in which that information can be used. Wavelength differences in the light out there become coded as 'colour' differences in the computer model in the head. Shape and other attributes are encoded in the same kind of way, encoded into a form that is convenient to handle. The sensation of seeing is, for us, very different from the sensation of hearing, but this cannot be directly due to the physical differences between light and sound. Both light and sound are, after all, translated by the respective sense organs into the same kind of nerve impulses. It is impossible to tell, from the physical attributes of a nerve impulse, whether it is conveying information about light, about sound or about smell. The reason the sensation of seeing is so different from the sensation of hearing and the sensation of smelling is that the brain finds it convenient to use different kinds of internal model of the visual world, the world of sound and the world of smell. It is because we internally use our visual information and our sound information in different ways and for different purposes that the sensations of seeing and hearing are so different. It is not directly because of the physical differences between light and sound. "

46 " That was true, Iris would sometimes think, about marriage: it was only a boat, too. A wooden boat, difficult to build, even more difficult to maintain, whose beauty derived at least in part from its unlikelihood. Long ago the pragmatic justifications for both marriage and wooden-boat building had been lost or superseded. Why invest countless hours, years, and dollars in planing and carving, gluing and fastening, caulking and fairing, when a fiberglass boat can be had at a fraction of the cost? Why struggle to maintain love and commitment over decades when there were far easier ways to live, ones that required no effort or attention to prevent corrosion and rot? Why continue to pour your heart into these obsolete arts? Because their beauty, the way they connect you to your history and to the living world, justifies your efforts. A long marriage, like a classic wooden boat, could be a thing of grace, but only if great effort was devoted to its maintenance. At first your notions of your life with another were no more substantial than a pattern laid down in plywood. Then year by year you constructed the frame around the form, and began layering memories, griefs, and small triumphs like strips of veneer planking bent around the hull of everyday routine. You sanded down the rough edges, patched the misunderstandings, faired the petty betrayals. Sometimes you sprung a leak. You fell apart in rough weather or were smashed on devouring rocks. But then, as now, in the teeth of a storm, when it seemed like all was lost, the timber swelled, the leak sealed up, and you found that your craft was, after all, sea-kindly. "

48 " Yet a much more fundamentally political dimension of the socially constructed nature of capital - nothing less than the specification of a parallel universe with its own natural laws and rules for the physical existence and subsistence of financial capital and its interaction with the other factors of production - has also often been overlooked in contemporary academic literature. Under the current monetary arrangements financial capital is a peculiar creature indeed. Money can be created ex nihilo at the stroke of a pen - or a keyboard - by a specific type of legal person entrusted with the task, not other legal or natural person. With the socially constructed ability to attract compound interest in a world where physical assets rot and break, it does not share the same physical reality with the mere mortal factors of production: even in cases where productive investments which enable the payment of interest in real terms can be identified, the compounding of interest on financial capital is not temporally limited to the period that the relevant physical assets can continue to produce exponential returns in real terms. Rather than representing accumulated wealth that could be " saved" to finance investment, the bulk of money disappears as soon as other factors of production are not willing to pay a tribute to induce its continuing circulation in the form of interest payments. In addition to the inherently political nature of specifications of money have been detached from virtually any substantive connection to the rules or the realities experienced by other factors of production in the physical world that is nonetheless supposed to achieve economic efficiency and a host of other objectives through monetary calculation and monetarily mediated social relationships deserves particular scrutiny.
