Vice (n.) is contagious, and there is no trusting the sound and the sick together.
Vice (n.) is a group effort: we shove one another into it — and how is anyone to be saved with no one to hold him back and the whole human race urging him on?
Vice (n.) is always in rebellion against nature: luxury rejoices in the twisted and wants not merely to stray from the straight but to get as far from it as it can and stand directly against it.
Vice (n.) is the one thing we condemn but do not forsake — and the study of nature is a remedy against them that is plainer than anything visible.
Vice (n.) is the one task we pursue with our whole minds and have not yet finished: luxury is still discovering new things to go crazy over.
Vice (n.) in remission returns with compound interest: an interval of virtue is abeyance, not absence.
Vice (n.) is incurable when it has become habit, and when men are not only attracted but pleased by shameful things.
Vice (n.) is a crowd effect: we push one another into it — how can a man be recalled when none restrain him and all mankind urge him on?
Vice (n.) is dissatisfied with itself and with all its fellows — evil men think ill of evil men too.
Vice (n.) that is powerless escapes notice, like a poisonous snake handled while stiff with cold: the poison is not lacking, only numbed — give such men power equal to their wishes and you will see.
Vice (n.) creep into our hearts under the names of virtues: rashness passes for bravery, moderation is called sluggishness, and the coward is thought prudent.
Vice (n.) as a disease of the soul reverses the body's case — the worse it is, the less one perceives it, as deep sleep annihilates even dreams.
Vice (n.) do not merely defile us; we are dyed by them.
Vice (n.) is catching: a pampered friend softens you, a rich neighbour gives you cravings, a spiteful companion rubs his rust onto the most innocent heart.
Vice (n.) never settles: it keeps changing, not for the better, only into new forms, while a good way of life satisfies and stays.
Vice (n.) is the reverse of bodily illness: the worse a person is, the less he feels it, as the deepest sleep blots out even dreams.
Vice (n.) is most dangerous when it looks cured; out in the open it turns moderate, as a disease is half-healed once it breaks the surface.
Vice (n.) is not around you but within you: the miser, the swindler and the bully you dread are already inside.
Vice (n.) is always at war with nature: luxury delights not just in straying from the right course but in going as far from it as it can.
Vice (n.) is manifold and beyond classification: devotion to the right is simple, devotion to the wrong admits infinite variations.
