長くて申し訳ありませんがどなたかお願いいたします。 THE WORD philosophy means the love of wisdom, but what phi-lospphers really love is reasoning. They formulate theories and marshal reasons to support them, they consider objections and try to meet these, they construct arguments against other views. Even philosophers who proclaim the limitations of reason−the Greek skep-tics, David Hume, doubters of the objectivity of science−all adduce reasons for their views and present difficulties for opposing ones. Proclamations or aphorisms are not considered philosophy unless they also enshrine and delineate reasoning. One thing philosophers reason about is reasoning itself. What prin-ciples should it obey? What principles must it obey? Aristotle initiated the explicit formulation and study of deductive principles, writers on science and support, Descartes attempted to show why we should trust the results of reasoning, Hume questioned the rationality of our doing so,and Kant demarcated what he held to be reason`s proper domain. This delineation of reason was not an academic exercise. Discoveries were to be applied: people`s reasoning was to be improved, their be-liefs and practices and actions made more rational. Inquiring into the rationality of contemporary beliefs and practices carries risks, Socrates discovered. The traditions of a society sometimes do not withstand scrutiny; not everyone wishes to see the implicit examined explicitly. Even the simple consideration of alternatives can seem a corrosive undercutting of what actually exists, an exposure of arbitrariness.
