Finding nice impersonal passive example from Seneca (Moral Letters 30): ubi plurimis locis laxari coepit [navis?] et cedere, succurri non potest navigio dehiscenti, made me ask two things:
Could we simply replace the passive succurri with the active succurrere? If so, what is the difference in meaning? Another example from Cicero (collected by Mitomino): Negat Epicurus iucunde posse vivi, nisi cum virtute vivatur - is it possible to switch to vivere?
In general, can impersonal passive clause can be the subject and attach with simple verbs like infinitives sometimes do? Like my example: "malis seccurri, bonos vexat"?
