 By contrast, the Platonic tradition, principally through the influence of Augustine, writing in the fourth and fifth centuries, is associated with the view that the mind “gains the knowledge of [itself] through itself” (On the Trinity 9.3; Matthews 1992; Cary 2000) by being present to itself. Thus, on this view, self-awareness requires no awareness of outer things. In a similar vein, in the eleventh century, Avicenna argues, by way of his Flying Man thought experiment, that a newly created person floating in a void, with all senses disabled, would nevertheless be self-aware. Thus the self that one cognises cannot be a bodily thing of which one is aware through the senses (Kaukua &amp; Kukkonen 2007; Black 2008; Kaukua 2015). On such views, and in contrast to the Aristotelian picture, basic self-awareness is neither sensory in nature nor dependent on the awareness of other things. This latter claim was accepted by Aquinas, writing in the thirteenth century, who can be seen as synthesising aspects of the Platonic and Aristotelian traditions (Cory 2014). For not only does Aquinas claim that there is a form of self-awareness—awareness that one exists—for which, “the mere presence of the mind suffices”, there is another form—awareness of one’s essence—that, as Aristotle had claimed, is dependent on cognising other things and so for which “the mere presence of the mind does not suffice” (Summa 1, 87, 1; Kenny 1993: ch. 10).
