VanderMey, Randall et al. (2011). Comp, p. 183: "Bare assertion. The most basic way to distort an issue is to deny that it exists. This fallacy claims, 'That's just how it is.'"
Angelus Politianus,Angelo Poliziano's Lamia: Text, Translation, and Introductory Studies, (2010), p. 26. Locus: "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."

Jeremy Bentham (1834), Deontology; or, The science of morality, vol. 1, p. 323; locus: "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."
Jeremy Bentham (1838), Works of Jeremy Bentham, p. 192. Locus: "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."
