''Philosophy in Science: An Historical Introduction''. Springer, 2011, p. 118ff.〕 ==Worlds 1, 2 and 3== Popper split the world into three categories: * World 1: the world of physical objects and events, including biological entities * World 2: the world of mental objects and events * World 3: objective knowledge. 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「Popper's three worlds」の詳細全文を読む スポンサード リンク
