Meaning ever more. Alexis in Atthis [writes]: "how Zeus casts clouds at first quietly, then more and more."[1] Anaxilas in Hours [and] Alexis in Pezonike [sc. also use the phrase].[2]
This 'more' is said affirmatively, as [in] 'a pirate is no more evil than a liar'. But by the Skeptics it is said not positively, but negatively: as by someone who in refutation says, 'Scylla did not exist, any more than Chimaera did'. And sometimes it is used comparatively, as when we say 'honey is more sweet than grapes'; while sometimes it is used both positively and negatively, as when we say 'virtue does more good than harm'. For [by that] we mean that virtue does good, but does not do harm.[3]
