Poliziano, Angelo. (2010). Angelo Poliziano's Lamia: Text, Translation, and Introductory Studies, p. 26; excerpt, "In Cicero's De natura deorum, as well as in other sources, the phrase “Ipse dixit” pointed to the notion that Pythagoras's disciples would use that short phrase as justification for adopting a position: if the master had said it, it was enough for them and there was no need to argue further."
Benthem, Jeremy. (1834). Deontology; or, The science of morality, Vol. 1, p. 323; excerpt, "ipsedixitism ... comes down to us from an antique and high authority, —-it is the principle recognised (so Cicero informs us) by the disciples of Pythagoras. Ipse (he, the master, Pythagoras), ipse dixit, -—he has said it; the master has said that it is so; therefore, say the disciples of the illustrious sage, therefore so it is."
Benthem, Jeremy. (1838). Works of Jeremy Bentham, p. 192; excerpt, "... it is not a mere ipse dixit that will warrant us to give credit for utility to institutions, in which not the least trace of utility is discernible."
