Causal thinking is the result of the causal principle (or causality) which according to the German philosopher Kant is defined as follows: :"Everything that happens (begins to be) presupposes something from which it follows in accordance with a rule".〔Cited from William A. Harper and Ralf Meerbote (eds.), ''Kant on Causality, Freedom, and Objectivity'', University of Minnesota Press, Minneapolis, p. 4, 1984. ISBN 0-8166-1266-8〕 ==Basic considerations== Although the belief in causality determines essentially the development of humanity, it suffers a number of drawbacks: :"It will now be obvious that the concept of cause, as used in our practical Weltanschauung suffers from lack of clearness – perhaps, also, from inherent contradictions. Partly in consequence of such obscurities and partly because of the metaphysical implications of the concept, it has undergone modifications at the hands of natural science; and 'cause' is now being eliminated from scientific terminology altogether."〔James Hastings and John A. Selbie, ''Encyclopedia of Religion and Ethics Part 5'', Kessinger Pub Co, Whitefish, MT, p. 263, 2003. ISBN 0-7661-3675-2〕 Instead of using the term causality physics uses the following paraphrase: :"From appreciation of these difficulties and metaphysical mysteries, science, and empiricist philosophy steeped in science, came to speak of an event as the cause of another only in the sense that it is a real condition, on the occurrence of which something else happens which would not happen without it. A cause, in fact, becomes a sine qua non antecedent, but does not itself necessarily 'produce' the event which is called effect." This change in the way of speaking in science does not affect causal thinking particularly because the scientific approach and the scientific rules and laws remained unchanged. The scientific approach is built on the assumption that any development may be represented by an alternating sequence of causes and effects, where the last effect is the cause of the next effect. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Causal thinking」の詳細全文を読む スポンサード リンク
