The first thing that happens to men once they have had to give up any pleasure, whether for propriety’s sake, or from satiety, or for their health, is to condemn it in other people. Such behavior implies a sort of attachment to the very things one has just renounced: we want nobody else to enjoy the good things that we have lost; it is a feeling of jealousy.

[La première chose qui arrive aux hommes après avoir renoncé aux plaisirs, ou par bienséance, ou par lassitude, ou par régime, c’est de les condamner dans les autres. Il entre dans cette conduite une sorte d’attachement pour les choses mêmes que l’on vient de quitter; l’on aimerait qu’un bien qui n’est plus pour nous ne fût plus aussi pour le reste du monde: c’est un sentiment de jalousie.]

The first thing men do, when they have renounc'd pleasure, either out of decency, surfeit, or conviction, is to condemn it in others. This sort of management is however seldom free from a particular affection for those very things they left off, but they would have no body enjoy the pleasure they can no longer enjoy themselves, which proceeds more from Jealousie than any thing else.
[Bullord ed. (1696)]

The first thing Men do, when they have renounc'd Pleasure, either out of Decency, Surfeit, or Conviction, is to condemn it in others. They preserve, in this Conduct, a sort of Affection for the very things they left off; they would have no body enjoy the Pleasure they can no longer enjoy themselves: 'Tis a sentiment of Jealousy.
[Curll ed. (1713)]

The first Thing, when Men have renounced Pleasure, either out of Decency, Satiety, or Necessity, is to condemn it in others. This Sort of Reproof, however, is not free from a latent Affection for their forsaken Pleasures; they would interdict to all others what they can themselves no longer enjoy; their Admonitions are the Snarlings of Jealousy, not the Dictates of Purity.
[Browne ed. (1752)]

The first thing men do when they have renounced pleasure, through decency, lassitude, or for the sake of health, is to condemn it in others. Such conduct denotes a kind of latent affection for the very things they left off; they would like no one to enjoy a pleasure they can no longer indulge in; and thus they show their feelings of jealousy.
