A quote
Armies have endured all manner of want, have lived on roots, and have resisted hunger by means of food too revolting to mention. All this they have suffered to gain a kingdom, and,—what is more marvellous,—to gain a kingdom that will be another’s. Will any man hesitate to endure poverty, in order that he may free his mind from madness? Therefore one should not seek to lay up riches first; one may attain to philosophy, however, even without money for the journey.
