This might suggest that Grosseteste reserves the notion of mental illumination simply for the proper operation of the intellective part of the soul.
Mental vision and an illumination of the mind are involved even in the operation of our rational power in demonstrative science.
Nevertheless, Aristotle does discuss the source of the principles and definitions employed in demonstrations, and it is in considering these remarks, in particular, that Grosseteste introduces the ideas of mental vision and the illumination of the mind.
He expresses this experience of illumination given after mental striving in terms of the city seen intermittently by the approaching pilgrim or of the spirit breaking through the hard rind of the letter.
To start with, we found that both the seasonal changes in mood and behavior and the experienced illumination indoors contributed independently to mental well-being, since both the GSS (t = 12.63, P < 0.001) and the illumination score (t = 2.92, P = 0.0035) were significantly associated with the GHQ-12 sum score in the two univariate regression models.
For some of the important topics discussed in the area of medieval epistemology, see the articles divine illumination, medieval theories of demonstration, and mental representation in medieval philosophy.
Its central theme is the conviction that, by applying the classical methods of mental prayer, one experiences a contemplative "vision of light," a symbolic term denoting the intuitional illumination that the mystic realizes in his encounter with the Divine Unknown.
Our findings herein suggest that illumination levels indoors are of importance to mental well-being.
The light patterns were recorded by a cooled digital camera once per second, and average illumination levels of these images were compared in counterbalanced mental blocking versus nonblocking conditions.
Greater seasonal changes (P < 0.001) and poor illumination indoors (P = 0.0035) were associated with more severe mental ill-being.
On the other hand, greater seasonal changes and poor illumination indoors are significant factors which were associated with worse mental ill-being.
