Ingratitude is the lack of gratidute, thanklessness for the things for which one should be thankful.
- Deserted, at his utmost need,
By those his former bounty fed;
On the bare earth exposed he lies,
With not a friend to close his eyes.
- John Dryden, Alexander's Feast (1697), Stanza 4.
- A man is very apt to complain of the ingratitude of those who have risen far above him.
- Blow, blow, thou winter wind,
Thou art not so unkind
As man's ingratitude:
Thy tooth is not so keen,
Because thou art not seen,
Although thy breath be rude.
- Ingratitude is monstrous; and for the multitude to be ingrateful, were to make a monster of the multitude.
- This was the most unkindest cut of all;
For when the noble Cæsar saw him stab,
Ingratitude, more strong than traitor's arms,
Quite vanquish'd him; then burst his mighty heart;
And, in his mantle muffling, up his face,
Even at the base of Pompey's statue,
Which all the while ran blood, great Cæsar fell.
- Ingratitude! thou marble-hearted fiend,
More hideous, when thou show'st thee in a child,
Than the sea-monster!
- All the stor'd vengeances of heaven fall
On her ungrateful top.
- What, would'st thou have a serpent sting thee twice?
- I hate ingratitude more in a man,
Than lying, vainness, babbling, drunkenness,
Or any taint of vice.
