“A bear, however hard he tries, grows tubby without exercise.”

“A mind without instruction can no more bear fruit than can a field, however fertile, without cultivation.”
A: Quod est enim maius argumentum nihil eam prodesse quam quosdam perfectos philosophos turpiter vivere? M: Nullum vero id quidem argumentum est. Nam ut agri non omnes frugiferi sunt qui coluntur [...] sic animi non omnes culti fructum ferunt. Atque, ut in eodem simili verser, ut ager quamvis fertilis sine cultura fructuosus esse non potest, sic sine doctrina animus; ita est utraque res sine altera debilis. Cultura autem animi philosophia est; haec extrahit vitia radicitus et praeparat animos ad satus accipiendos eaque mandat eis et, ut ita dicam, serit, quae adulta fructus uberrimos ferant.

“A Judge must bear in mind that when he tries a case he is himself on trial.”

“Unchanged within, to see all changed without,
Is a blank lot and hard to bear, no doubt.”

“Pain is hard to bear," he cried,
"But with patience, day by day,
Even this shall pass away.”

“Trees that are slow to grow bear the best fruit.”

“To supply a thought is mental massage; but to evolve a thought of your own is an achievement. Thinking is a brain exercise — and no faculty grows save as it is exercised.”

“Yet God hath not only granted these faculties, by which we may bear every event without being depressed or broken by it, but like a good prince and a true father, hath placed their exercise above restraint, compulsion, or hindrance, and wholly without our own control.”

“Things that were hard to bear are sweet to remember.”
