A quote
Wisdom is a large and spacious thing. It needs plenty of free room. One must learn about things divine and human, the past and the future, the ephemeral and the eternal; and one must learn about Time. See how many questions arise concerning time alone: in the first place, whether it is anything in and by itself; in the second place, whether anything exists prior to time and without time; and again, did time begin along with the universe, or, because there was something even before the universe began, did time also exist then?
