Marcus Tullius Cicero,
Cicero's Tusculan Disputations
“ For as every disorder or perturbation is a motion of the mind, either devoid of reason, or in despite of reason, or in disobedience to reason, and as that motion is excited by an opinion of either good or evil; these four perturbations are divided equally into two parts: for two of them proceed from an opinion of good, one of which is an exulting pleasure, that is to say, a joy elated beyond measure, arising from an opinion of some present great good ”
