For 'aid' Mason and Collier's folio read aim.
Act III.
Sc. 1.
"As true as I believe you think them false."
The poet probably wrote 'you'll' think.
"I will instruct my sorrows to be proud;
For Grief is proud, and makes his owner stoop."
Hanmer reads stout for 'stoop,' but I see no need of change. We talk of a person being bowed to the earth with grief, and this is what the poet meant. 'Owner' was used of one who simply had, as "But like the owner of a foul disease" (Ham. iv. 1).
