On the Work of Distinction in Itself
We must consider next the work of distinction in itself. First, the work of the first day; secondly, the work of the second day; thirdly the work of the third day.Under the first head there are four points of inquiry:
- Whether the word light is used in its proper sense in speaking of spiritual things?
- Whether light, in corporeal things, is itself corporeal?
- Whether light is a quality?
- Whether light was fittingly made on the first day?
