Questa vita terrena è quasi un prato, che 'l serpente tra' fiori et l'erba giace; et s'alcuna sua vista agli occhi piace, è per lassar piú l'animo in… - Petrarch

Certamente la solitudine senza lettere è una prigione, ed è uno gravissimo supplizio; ma dàgli le lettere, e li è la patria, li è la libertade, li è il piacere.

I closed the book*, angry with myself that I should still be admiring earthly things who might long ago have learned from even the pagan philosophers that nothing is wonderful but the soul, which, when great itself, finds nothing great outside itself. Then, in truth, I was satisfied that I had seen enough of the mountain; I turned my inward eye upon myself, and from that time not a syllable fell from my lips until we reached the bottom again... [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.

Truly, we are dust and shadow; truly, desire is blind and greedy; truly, hope deceives.
