Acção e Razão

Todas as decisões tomadas por um indivíduo que se expressam em acções são, por definição, racionais - já que todas as acções são o produto do uso da Razão para uma avaliação e escolha prévia de meios para atingir um determinado fim. Informação perfeita ou imperfeita é uma consideração à parte, e que em nada altera o facto de que toda acção é racional. 

Mises sumariza-o desta forma: «When applied to the means chosen for the attainment of ends, the terms rational and irrational imply a judgment about the expediency and adequacy of the procedure employed. The critic approves or disapproves of the method from the point of view of whether or not it is best suited to attain the end in question. It is a fact that human reason is not infallible and that man very often errs in selecting and applying means. An action unsuited to the end sought falls short of expectation. It is contrary to purpose, but it is rational, i.e., the outcome of a reasonable—although faulty—deliberation and an attempt—although an ineffectual attempt—to attain a definite goal. The doctors who a hundred years ago employed certain methods for the treatment of cancer which our contemporary doctors reject were—from the point of view of present-day pathology—badly instructed and therefore inefficient. But they did not act irrationally; they did their best. It is probable that in a hundred years more doctors will have more efficient methods at hand for the treatment of this disease. They will be more efficient but not more rational than our physicians.» (Human Action, p. 20)
