From the article "Angel/Angelogy", by E. Ann Matter, in the Dictionary of the Middle Ages. "Aquinas devoted fourteen books of the Summa Theologiae to the nature and powers of angels. he held that angels have form but not matter, and are therefore eternal and incorruptible. Angels are able to assume bodies; these bodies can take up space, so only one angel can be in a particular place at a certain time. In contrast, Duns Scotus asserted that angels consist of both form and a noncorporeal matter particular to them alone, which makes it possible for more than one angel to occupy the same place at the same time (De Anima, XV: De rerum principio, VII-VIII). The ensuing debates over these positions may have given rise to the early modern legend that the Scholastics argued over such questions as how many angels can dance on the head of a pin."
The feature show for this week's Shakedown Stream contained a Let It Grow coming out of Terrapin Station in the 2nd set that is amazing (one of the best I have heard). The boys jam the tune for well over 20 minutes before going into drumz.
