Rarely the Infinitive is used exactly like the Accusative of a noun:— beātē vīvere aliī in aliō, vōs in voluptāte pōnitis (Fin. 2.86) , a happy life different [philosophers] base on different things, you on pleasure. quam multa ... facimus causā amīcōrum, precārī ab indīgnō, supplicāre , etc. (Lael. 57) , how many things we do for our friends' sake , ask favors from an unworthy person, resort to entreaty , etc. nihil explōrātum habeās, nē amāre quidem aut amārī ( id . 97), you have nothing assured, not even loving and being loved. Many complementary and other constructions approach a proper accusative use of the infinitive, but their development has been different from that of the examples above. Thus, avāritia ... superbiam , crūdēlitātem , deōs neglegere , omnia vēnālia habēre ēdocuit (Sall. Cat. 10 ), avarice taught pride, cruelty , to neglect the gods , and to hold everything at a price.
