Is there a saying in classical Latin similar to "all or nothing"? I am aware of aut Caesar aut nihil, and that would be fine if it was classical. In most cases the era of origin is irrelevant, but I would like to know whether a similar quote is found in classical authors.
Taking the following as an example:
seu nihil militi, sive omnia concederentur
concede either nothing to the army, or everything
Tacitus, Annals, 1.36
we could perhaps adapt it to: seu nihil sive omnia
I can't think of a phrase from classical Latin, but I should think that nihil nisi omnia would be all right. The meaning is quite clear, and it sounds snappy enough.
