Mister Cameron - I have read the unexpurgated Ovid, the love poems of Sappho, the Decameron in the original, and a great many texts in Greek and Latin histories that were not though fit for proper gentlemen to read, much less proper ladies. I know in precise detail what Caligula did to, and with, his sisters, and I can quote it to you in Latin or in my own translation if you wish. I am interested in historical truth, and truth in history is often unpleasant and distasteful to those of fine sensibility. I frankly doubt that you will produce anything to shock me.

The difficulty of learning the dead languages does not arise from any superior abstruseness in the languages themselves, but in their being dead, and the pronunciation entirely lost. It would be the same thing with any other language when it becomes dead. The best Greek linguist that now exists does not understand Greek so well as a Grecian plowman did, or a Grecian milkmaid; and the same for the Latin, compared with a plowman or a milkmaid of the Romans; and with respect to pronunciation and idiom, not so well as the cows that she milked. It would therefore be advantageous to the state of learning to abolish the study of the dead languages, and to make learning consist, as it originally did, in scientific knowledge.

E quindi uscimmo a riveder le stelle.And so we came forth, and once again beheld the stars.

Saepe creat molles aspera spina rosas - Often the prickly thorn produces tender roses

Non est ad astra mollis e terris via - There is no easy way from the earth to the stars

Pactum serva - Keep the faith

Status quo, you know, is Latin for 'the mess we're in'.
