Context

“Yes, I replied; but that surely is what ought not to be, as the argument has just proved to us; and by that proof we must abide until it is disproved by a better.

Then persons of worth, even if only mortal men, must not be represented as overcome by laughter, and still less must such a representation of the gods be allowed. Still less of the gods, as you say, he replied.
Then we shall not suffer such an expression to be used about the gods as that of Homer when he describes how
'Inextinguishable laughter arose among the blessed gods, when they saw Hephaestus bustling about the mansion.'
