Illuminationism is a doctrine according to which the process of human thought needs to be aided by divine grace. It is the oldest and most influential alternative to naturalism in the theory of mind and epistemology.〔(Stanford Encyclopedia of Philosophy )〕 It was an important feature of ancient Greek philosophy, Neoplatonism, medieval philosophy, and in particular, the Illuminationist school of Islamic philosophy. ==Early history== Socrates says in The Apology that he had a divine or spiritual sign that began when he was a child. It was a voice that turned him away from something he was about to do, although it never encouraged him to do anything. Apuleius later suggested the voice was of a friendly demon 〔''De deo Socratis'', XVII–XIX)〕 and that Socrates deserved this help as he was the most perfect of human beings. The early Christian philosopher Augustine (354 – 430) also emphasised the role of divine illumination in our thought, saying that "The mind needs to be enlightened by light from outside itself, so that it can participate in truth, because it is not itself the nature of truth. You will light my lamp, Lord 〔''Confessions'' IV.xv.25〕 and "You hear nothing true from me which you have not first told me.〔''Confessions'' X.ii.2〕 Augustine's version of illuminationism is not that God gives us certain information, but rather gives us insight into the truth of the information we received for ourselves. :If we both see that what you say is true, and we both see that what I say is true, then where do we see that? Not I in you, nor you in me, but both of us in that unalterable truth that is above our minds.〔''Confessions'' XII.xxv.35〕 Augustine's theory was defended by Christian philosophers of the later Middle Ages, particularly Franciscans such as Bonaventura and Matthew of Aquasparta. According to Bonaventura: :Things have existence in the mind, in their own nature (''proprio genere''), and in the eternal art. So the truth of things as they are in the mind or in their own nature – given that both are changeable – is sufficient for the soul to have certain knowledge only if the soul somehow reaches things as they are in the eternal art.〔''De scientia Christi'', q.4 resp〕 The doctrine was criticised by John Pecham and Roger Marston, and in particular by Thomas Aquinas, who denied that in this life we have divine ideas as an object of thought, and that divine illumination is sufficient on its own, without the senses. Aquinas also denied that there is a special continuing divine influence on human thought. People have sufficient capacity for thought on their own, without needing "new illumination added onto their natural illumination".〔''Summa theologiae'' 1a2ae 109.1c〕 The theory was defended by Henry of Ghent. Henry argued against Aquinas that Aristotle's theory of abstraction is not enough to explain how we can acquire infallible knowledge of the truth, and must be supplemented by divine illumination. A thing has two exemplars against which it can be compared. The first is a created exemplar which exists in the soul. The second is an exemplar which exists outside the soul, and which is uncreated and eternal. But no comparison to a created exemplar can give us infallible truth. Since the dignify of man requires that we can acquire such truth, it follows that we have access to the exemplar in the divine mind.〔''A Companion to Philosophy in the Middle Ages'', ed. Gracia and Noone〕 Henry's defence of illuminationism was strongly criticised by the Franciscan theologian Duns Scotus, who argued that Henry's version of the theory led to scepticism. 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「Illuminationism」の詳細全文を読む スポンサード リンク
