"If thou knowest," says Carneades, "of a serpent lurking in a place where, without suspicion, a person is going to sit down, by whose death thou expectest an advantage, thou dost ill if thou dost not give him caution of his danger; and so much the more because the action is to be known by none but thyself."
"Norbait, hik haren heriotzatik mozkin bat igurikatzen dualarik, oharkabean esertzera doan lekuan suge gorde bat dagoela baldin badakik, dio Karneadesek, gaizki egiten duk gaztigatzen ez badiok; eta hainbat gehiago non heure ekintza hik baizik ez baituk ezagutu behar".
