perseverate

Gli essercizii delle lettere ancora si truovano sottoposti a mille impeti della fortuna; ora mancano e' padri; ora seguano e' parenti invidiosi, duri, inumani: ora t'asalisce poverta, ora cadi in qualche infortunio, per modo che certo non puoi negare la fortuna ivi tenere gran parte d'imperio come sopra delle cose umane, cosi sopra gli studii tuoi, ne' quali tu non puoi molto perseverare sanza copia delle medesime umane cose sottoposte alla fortuna.

Even though the word "perseverance" (perseverare) ordinarily connotes activity and though in Definition 4 Newton writes that "a body perseveres in any new state solely by the force of inertia," nevertheless, the vis inertiae operates only (solommundo) during a body's change of state in response to an impressed force.
