The emotions [páthe] are all those affections which will cause men to change [metabállontes] their opinion in regard to their judgements [kríseis], and are accompanied by pleasure [hedoné] and pain [lypé]; such as anger [orgé], pity [éleos], fear [phóbos], and all similar emotions and their contraries.
