We are sinful not only because we have eaten of the Tree of Knowledge, but also because we have not yet eaten of the Tree of Life. The state in which we are is sinful, irrespective of guilt.
Youth is happy, because it has the ability to see beauty. When this ability is lost, wretched old age begins, decay, unhappiness.

We would be happy precisely if we had no books, and the kind of books that make us happy are the kind we could write ourselves if we had to.

A book must be the axe for the frozen sea inside us.
