It must be understood that prime matter, and form as well, is neither generated nor corrupted, because every generation is from something to something. Now that from which generation proceeds is matter, and that to which it proceeds is form. So that, if matter or form were generated, there would be a matter for matter and a form for form, endlessly. Whence, there is generation only of the composite, properly speaking.
Thomas AquinasFor those with faith, no evidence is necessary; for those without it, no evidence will suffice.
Thomas AquinasIn order for a war to be just, three things are necessary. First, the authority of the sovereign... Secondly, a just cause... Thirdly... a rightful intention.
Thomas AquinasGiven the sin of impiety through which they [the Romans] sinned against the divine nature [by idolatry], the punishment that led them to sin against their own nature followed.... I say, therefore, that since they changed into lies [by idolatry] the truth about God, He brought them to ignominious passions, that is, to sins against nature; not that God led them to evil, but only that he abandoned them to evil.
Thomas Aquinas
