Wisdom without love is like having lungs but no air to breathe. Do not seek wisdom in order to acquire knowledge but in order to live and love more fully.
My aim is to understand love. I know how alive I felt when I was in love, and I know that everything I have now, however interesting it might seem, doesn't really excite me.
But love is a terrible thing: I've seen my girlfriends suffer and I don't want the same thing to happen to me. [...] Although my aim is to understand love, and although I suffer to think of people to whom I gave my heart, I see that those who touched my heart failed to arouse my body, and that those who aroused my body failed to touch my heart.
I never had any other desire so strong, and so like covetousness, as that ... I might be master at last of a small house and a large garden, with very moderate conveniences joined to them, and there dedicate the remainder of my life to the culture of them and the study of nature.
For the salvation of his soul the Muslim digs a well. It would be a fine thing if each of us were to leave behind a school, or a well, or something of the sort, so that life would not pass by and retreat into eternity without a trace.
