Hope is a sarcasm. [ Alfred Mercier ]

Neither irony nor sarcasm is argument. [ Rufus Choate ]

It is better to sacrifice one's love of sarcasm than to indulge it at the expense of a friend.

The best philosophy to employ toward the world is to alloy the sarcasm of gayety with the indulgence of contempt. [ Chamfort ]

Oh! woe to him who first had the cruelty to ridicule the name of old maid, a name which recalls so many sorrowful deceptions, so many sufferings, so much destitution! Woe to him who finds a target for his sarcasm in an involuntary misfortune, and who crowns white hair with thorns! [ E. Souvestre ]
