Moderation is the feebleness and sloth of the soul, whereas ambition is the warmth and activity of it.
Francois de La Rochefoucauld

No man deserves to be praised for his goodness, who has it not in his power to be wicked. Goodness without that power is generally nothing more than sloth, or an impotence of will.
Francois de La Rochefoucauld

Nothing irritates me more than chronic laziness in others. Mind you, it's only mental sloth I object to. Physical sloth can be heavenly.
Elizabeth Hurley

Sloth, not ill-will, makes me unjust.
Mason Cooley

The Bible and several other self help or enlightenment books cite the Seven Deadly Sins. They are: pride, greed, lust, envy, wrath, sloth, and gluttony. That pretty much covers everything that we do, that is sinful... or fun for that matter.
Dave Mustaine

The kindest word to describe my performance in school was Sloth.
Harrison Ford

Thou seest how sloth wastes the sluggish body, as water is corrupted unless it moves.
Ovid

We excuse our sloth under the pretext of difficulty.
Quintilian

You must avoid sloth, that wicked siren.
Horace
