Takes an original approach to reading Augustine's theory of divine illumination and shows how the theory was transformed and reinterpreted in medieval ...

The prevailing interpretation of Augustine’s theory of divine illumination suggests that illumination provides the human mind with the content of our a priori concepts. While there is strong textual evidence to support this view, I contend it offers an incomplete picture of the work illumination does in Augustine’s epistemology. Based on an analysis of Augustine’s solution to the paradox of language acquisition in De magistro, I argue illumination also supplies the mind with the content of all our empirical concepts. In this text, Augustine calls our attention to the problem that learning the meaning of words by even the simplest of means—through direct acquaintance (i.e., by having an object pointed out to us and labeled with a name)—turns out to require a relatively sophisticated grasp of the word’s usage in the first place, one that depends on illumination to provide the content of all our universal concepts.

This paper proposes a new approach to Augustine’s illumination theory, understanding illumination as resulting from an act of the human being as much as from an action of God. Regardless of God’s ever present light, the human intellect is not constantly and indiscriminately illuminated. In order to explain how the human intellect attains knowledge to different degrees, and how it can resist the divine light without being actually able to deny it, I will make use of two concepts Augustine himself did not employ : the first one is relationship, the second, referring to God, is being-for-others. As being-for-others, God gives the human being not the gift of knowledge, but that of the relationship with Him (as Truth and Wisdom), by means of which the human being can attain knowledge. By placing Himself in relationship with the human being, God grants it the freedom and power to cooperate in divine actions : re-creation after the fall (formatio), illumination and salvation. If passive, the human intellect does not receive knowledge, it is only in its turning towards the ever present light of Truth that it sees the intelligible truths in the divine light, and it is able to do so to the extent of one’s good will, or one’s love (caritas). Augustine sees illumination as a joint action of God and human being, depending on human being no less than on God. The concept of relationship and the understanding of God as being-for-others explain why no illumination will take place without the active role of the human intellect, why the divine light is not coercive, and why Augustine considers the necessity of both human freedom and God’s power in the act of knowledge.

This paper argues that structural elements of Bonaventure’s illumination theory significantly parallel Kantian transcendental philosophy. The question of whetherand what elements of transcendental thought can be found in Bonaventure’s philosophy is potentially instructive both for understanding medieval influences on transcendental philosophy and for raising the philosophical question of why substantially similar premises and thought-patterns result in substantially different solutions. After defining what I mean by “transcendental philosophy” and justifying that definition I turn to Bonaventure’s illumination theory and highlight thought patterns parallel to Kantian transcendental philosophy that emerge in Bonaventure’s epistemology. Finally, I discuss how their differences help us to understand the variations in medieval and modern solutions to what is sometimes termed “the transcendental problem.”.

Collapsing three-dimensional space into two violates Lehar's “volumetric mapping” constraint and can cause the visual system to construct illusory transparent regions to replace voxels that would have contained illumination. This may underlie why color constancy is worse in two dimensions, and argues for Lehar to revise his phenomenal spatial model by putting “potential illumination” in empty space.
