The quote Ted, Jr reads to Tawney, "Love may be of the seen and of the unseen, of the present, of the absent. Consequently, a thing to be loved is not so adapted to faith as a thing to be hoped for since hope is always of the absent and the unseen.", is from "On Faith and Reason" by Thomas Aquinas.
The book that Lezley mentions to Daniel is "Siddhartha" by Hermann Hesse.
