Opening credits: "We must, in my opinion, begin by distinguishing between that which is and never becomes, and that which is always becoming and never is". (Plato, Timaeus)
Closing credits: "Then it seems to me that I see myself dwelling, as it were, in some strange region of the universe which neither exists entirely in the slime of the earth nor entirely in the purity of Heaven; and that, by the grace of God, I can be transported from this inferior to that higher world..." (Abbot Suger, 1144)
