Knowledge is the eye of desire and can become the pilot of the soul.

What is not fully understood is not possessed.

Knowledge, like religion, must be "experienced" in order to be known.

---

Words are the leaves of the tree of language, of which, if some fall away, a new succession takes their place.

---

Every year, if not every day, we have to wager our salvation upon some prophecy based upon imperfect knowledge.

Poetry cannot be translated; and, therefore, it is the poets that preserve the languages; for we would not be at the trouble to learn a language if we could have all that is written in it just as well in a translation. But as the beauties of poetry cannot be preserved in any language except that in which it was originally written, we learn the language.
