Without Liberty, Law loses its nature and its name, and becomes oppression. Without Law, Liberty also loses its nature and its name, and becomes licentiousness.
— James Q. Wilson

Bad company is as instructive as licentiousness. One makes up for the loss of one's innocence with the loss of one's prejudices.
Denis Diderot licentious quote

Idleness is an inlet to disorder, and makes way for licentiousness. People who have nothing to do are quickly tired of their own company.
— Jeremy Collier

My English text is chaste, and all licentious passages are left in the obscurity of a learned language.
— Edward Gibbon

In the darkest hour through which a human soul can pass, whatever else is doubtful, this at least is certain. If there be no God and no future state, yet, even then, it is better to be generous than selfish, better to be chaste than licentious, better to be true than false, better to be brave than to be a coward. Blessed beyond all earthly blessedness is the man who, in the tempestuous darkness of the soul, has dared to hold fast to these venerable landmarks. Thrice blest is he who, when all is dreary and cheerless within and without, when his teachers terrify him, and friends shrink from him, has obstinately clung to moral good.
— licentious quotation by Frederick William Robertson
