It is one thing to remember, another to know. To remember is to safeguard something entrusted to the memory. But to know is to make each thing one's own, not depend on the text and always to look back to the teacher. "Zeno said this, Cleanthes said this." Let there be space between you and the book.
Seneca the YoungerWhatever we owe, it is our part to find where to pay it, and to do it without asking, too; for whether the creditor be good or bad, the debt is still the same.
