I have friends whose society is delightful to me; they are persons of all countries and of all ages; distinguished in war, in council, and in letters… - Petrarch

I am speaking to tell the truth, not from hatred or scorn of anyone.

Ma s'egli è amor, perdio, che cosa et quale?
Se bona, onde l'effecto aspro mortale?
Se ria, onde sí dolce ogni tormento?

[W]e look about us for what is to be found only within... How many times, think you, did I turn back that day, to glance at the summit of the mountain which seemed scarcely a cubit high compared with the range of human contemplation.

* Augustine's Confessions: And men go about to wonder at the heights of the mountains, and the mighty waves of the sea, and the wide sweep of rivers, and the circuit of the ocean, and the revolution of the stars, but themselves they consider not.
