The scholar without good breeding is a pedant; the philosopher, a cynic.

There is nothing so necessary, but at the same time there is nothing more difficult (I know it by experience) for you young fellows, than to know how to behave yourselves prudently towards those whom you do not like. Your passions are warm, and your heads are light; you hate all those who oppose your views, either of ambition or love; and a rival, in either, is almost a synonymous term for any enemy.

Whenever a man seeks your advice he generally seeks your praise.

Nothing sharpens the arrow of sarcasm so keenly as the courtesy that polishes it; no reproach is like that we clothe with a smile and present with a bow.

Let your enemies be disarmed by the gentleness of your manner, but let them feel at the same time the steadiness of your just resentment for there is a great difference between bearing malice, which is always ungenerous, and a resolute self-defense which is ever prudent and justifiable.

Little minds mistake little objects for great ones, and lavish away upon the former that time and attention which only the latterdeserve. To such mistakes we owe the numerous and frivolous tribe of insect-mongers, shell-mongers, and pursuers and driers of butterflies, etc. The strong mind distinguishes, not only between the useful and the useless, but likewise between the useful and the curious.

Real merit of any kind cannot long be concealed; it will be discovered, and nothing can depreciate it but a man exhibiting it himself. It may not always be rewarded as it ought; but it will always be known.
