It is generally said, "Past labors are pleasant," Euripides says, for you all know the Greek verse, "The recollection of past labors is pleasant."
[Lat., Vulgo enim dicitur, Jucundi acti labores: nec male Euripides: concludam, si potero, Latine: Graecum enim hunc versum nostis omnes: Suavis laborum est proeteritorum memoria.
All men have a feeling, that they would rather you told them a civil lie than give them a point blank refusal.... If you make a promise, the thing is still uncertain, depends on a future day, and concerns but few people; but if you refuse you alienate people to a certainty and at once, and many people too.
If you pursue good with labor, the labor passes away but the good remains; if you pursue evil with pleasure, the pleasure passes away and the evil remains.
Not to know what happened before you were born is to be a child forever. For what is the time of a man, except it be interwoven with that memory of ancient things of a superior age?
