Introduction
摘要
The discovery of the luminosity [Lucidität] of things is a great merit of the Greeks. By deepening into this knowledge, they reached a metaphysics of light. They were able to do so because they considered the world as a sensible symbol for a higher reality situated beyond, and therefore saw what is grasped through the senses as a path to the intelligible. The senses were not absolutized, but remained a passage. Thus, sensible light was a step towards the intelligible light.
