What the wise man does

“The wise man always has something to do. During the day he should be using his eyes for reading, his tongue for teaching, his hand for writing; at night his soul, free from the bondage of the body, should use both its rational faculty to descend to the corporeal realm and its intellective faculty to ascent to the incorporeal.” (William of Conches, A Dialogue on Natural Philosophy 2.1.1)
