Now for some of my favorite lines (I dog-eared my copy something fierce):
"It is better to have no work to do than work at nothing." So says Pliny, the fairly wealthy landowner, to a friend working too hard in the city, telling him to devote himself to literature or lesiure. His letters feature several lengthy descriptions of his villa at Laurentum; it's never been uncovered, but his description is so detailed that scholars have been able to precisely reconstruct it, as you can see here.
"...votes are counted, their value is not weighted, and no other method is possible in a public assembly. Yet this strict equality results in something very different from equity, so long as men have the same right to judge but not the same ability to judge wisely." Pliny is dissatisfied with the results of a corruption case decided by the Senate. Roman senators weren't democratically elected, but I think the point carries. People are stupid.
After failed crops at his other properties, Pliny says of his seaside villa: "For there I do most of my writing, and instead of the land I lack, I work to cultivate myself, so that I have a harvest in my desk to show you in place of full granaries elsewhere."
On a silver-tongued opponent in court: "Scarcely anyone has the gift of eloquence...but what Candidus calls loquacity is common to many people and the special gift of every impudent rascal."
To his friend, the historian Tacitus: "There may be writers who are ranked higher than either of us, but if we are classed together our position does not matter; for me the highest position is the one nearest to you." Aww. Buddies.
Pliny does not agree with Machiavelli in this advice to a friend, headed to take up the reins in a Greek province: "Affection is more effective than fear in gaining you your ends. Fear disappears at your departure, affection remains, and, whereas fear engenders hatred, affection develops into genuine regard." OK, technically I think M. said "It is better to be feared than loved, if you cannot be both" but who has ever been both, really?
Self-assurance is not an issue. "I do think all your written works are very fine, but especially those that deal with me. For...you are at your best in writing about your friends, and I find it your best when it is about myself."
Writing to his boss, the emperor Trajan, Pliny described a new religious sect as "nothing but a degenerate sort of cult carried to extravagant lengths." It was Christianity, of course.
