Here's from Hamlet, Act 1, Scene 2.
and yet, within a month,—
Let me not think on't,—Frailty, thy name is woman!—
A little month; or ere those shoes were old
With which she followed my poor father's body
Like Niobe, all tears;—why she, even she,—
O God! a beast that wants discourse of reason,
Would have mourn'd longer,—married with mine uncle,
My father's brother; but no more like my father
Than I to Hercules:
I think "a beast that wants discourse of reason, Would have mourn'd longer," is an apodosis of a conditional sentence whose protasis is omitted. Right? I wonder what the protasis is. Is it "if she(= Hamlet's mother) had been a beast that wants discourse of reason"?
