"The limit of quantity in pleasures is the removal of all that is painful. Wherever and whenever this is present, pleasure is no longer increased, but has reached its stationary maximum."

"The greatest good is to be found in the prudent management of the good things of life."

"The greatest disturbance of the soul is not pain, but the fear of pain."

"We must not violate nature, but obey her. And we shall obey her if we fulfill the necessary desires and also the natural, if they bring no harm, but sternly reject the harmful."

"The prudent man seeks not pleasure, but freedom from pain."
