It makes a great deal of difference whether one wills not to sin or has not the knowledge to sin.
Seneca the YoungerAs gratitude is a necessary, and a glorious virtue, so also it is an obvious, a cheap, and an easy one; so obvious that wherever there is life there is a place for it; so cheap, that the covetous man may be gratified without expense, and so easy that the sluggard may be so likewise without labor.
Seneca the YoungerPhilosophy is the art and law of life, and it teaches us what to do in all cases, and, like good marksmen, to hit the white at any distance.
Seneca the YoungerWhen thou hast profited so much that thou respectest even thyself, thou mayst let go thy tutor.
Seneca the YoungerJust as so many rivers, so many showers of rain from above, so many medicinal springs do not alter the taste of the sea, so the pressure of adversity does not affect the mind of the brave man. For it maintains its balance, and over all that happens it throws its own complexion, because it is more powerful than external circumstances.
