[Meaning he/she/it] theologizes, is puffed up.[1]
To dogmatize[2] is to set forth dogma, just as to legislate is to set forth laws. Dogmas are the name for two things: the thing opined and the opinion itself. Of these the thing opined is a proposition [protasis], and the opinion itself a conception [hypolepsis]. Now Plato ‘revealed’ things he understood; he ‘refuted’ false things; and he refrained from judgment concerning unclear things. And concerning the things which appeared correct to him, he revealed them through four characters, Socrates, Timaeus, the Athenian stranger, [the Eleatic stranger]. And the strangers are not, as some have understood, Plato and Parmenides, but nameless creations.
Concerning dogmas.[3] Some [consider a dogma] begotten [or generable], some unbegotten [or baseless]; and some [consider it] ensouled, some without soul.[4] When[5] Anaxagoras and Pythagoras went to Egypt and conferred with the wise men of Egyptians and the Hebrews there, they acquired their knowledge about the things that exist, and later Plato did so as well, as Plutarch says in his Parallel Lives. Indeed, Egyptians were the first to name the sun and the moon gods: they called the sun Osiris, and the moon Isis, since they saw these going at a run and running, [deriving the word] gods [theoi] from running [theein] and going.
