The ill-success of the projects of misdirected ingenuity has very naturally the effect of driving those men of practical skill, who, though without scientific knowledge, possess prudence and common sense, to the opposite extreme of caution, and of inducing them to avoid all experiments, and to confine themselves to the careful copying of successful existing structures and machines; a course which, although it avoids risk, would, if generally followed, stop the progress of all improvement. A similar course has sometimes... been adopted by men possessed of scientific as well as practical skill: such men having, in certain cases, from deference to popular prejudice, or from a dread of being reputed us theorists, considered it advisable to adopt the worse and customary design for a work in preference to a better but unusual design.

The development of economics as a science which is always based on human beings, the creative actors and protagonists in all social processes and events (the subjectivist conception), is undoubtedly the most significant and characteristic contribution made by the Austrian School of economics, founded by Carl Menger. In fact Menger felt it vital to abandon the sterile objectivism of the classical (Anglo-Saxon) school whose members were obsessed with the supposed existence of external objective entities (social classes, aggregates, material factors of production, etc.). Menger held that economists should instead always adopt the subjectivist view of human beings who act, and that this perspective should invariably exert a decisive influence on the way all economic theories are formulated, in terms of their scientific content and their practical conclusions and results.

Many people fail to grasp this point, apparently because they think of "scientific" evidence as only that produced in laboratories by controlled experiments. This leads them to treat field studies, however careful, thorough and well-documented, as "anecdotal"--mere preparation for the real thing, therefore properly ignored till it bears fruit entitled to be considered by learned persons. This attitude was much like that of cavalry generals in the First World War, waiting patiently for the infantry to clear the ground so that they could make the dashing charges that alone they thought entitled the name of warfare. Because these creatures are complex, only a tiny fraction of important truths about them can ever be seen in laboratories of expressed in control experiments. The same, of course, is true of the human race.

The work itself will cover a wide field including clearance of slums, which for adequate reasons cannot be undertaken by private capital; in rural housing of several kinds, where, again, private capital is unable to function; in rural electrification; in the reforestation of the great watersheds of the Nation; in an intensified program to prevent soil erosion and to reclaim blighted areas; in improving existing road systems and in constructing national highways designed to handle modern traffic; in the elimination of grade crossings; in the extension and enlargement of the successful work of the Civilian Conservation Corps; in non-Federal works, mostly self-liquidating and highly useful to local divisions of Government; and on many other projects which the Nation needs and cannot afford to neglect.

The Game of Chess is not merely an idle amusement; several very valuable qualities of the mind, useful in the course of human life, are to be acquired and strengthened by it, so as to become habits ready on all occasions; for life is a kind of Chess, in which we have often points to gain, and competitors or adversaries to contend with, and in which there is a vast variety of good and ill events, that are, in some degree, the effect of prudence, or the want of it. By playing at Chess then, we may learn: 1st, Foresight, which looks a little into futurity, and considers the consequences that may attend an action ... 2nd, Circumspection, which surveys the whole Chess-board, or scene of action: - the relation of the several Pieces, and their situations; ... 3rd, Caution, not to make our moves too hastily...
Benjamin Franklin
Development means a capacity for self-sustaining growth. It means that an economy must register advances which in turn will promote further progress. The loss of industry and skill in Africa was extremely small, if we measure it from the viewpoint of modern scientific achievements or even by standards of England in the late eighteenth century. However, it must be borne in mind that to be held back at one stage means that it is impossible to go on to a further stage. When a person was forced to leave school after only two years of primary school education, it is no reflection on him that he is academically and intellectually less developed than someone who had the opportunity to be schooled right through to university level. What Africa experienced in the early centuries of trade was precisely a loss of development opportunity, and this is of the greatest importance.
