“Doubt thou the stars are fire;Doubt that the sun doth move;Doubt truth to be a liar;But never doubt I love.”

“Modest doubt is call'd the beacon of the wise.”

“Too much of water hast thou poor Ophelia, and therefore I forbid my tears.But yet it is our trick, let shame say what it will. when these are gone the women will be out!Adieu my lord, I have a speech of fire that fane would blaze, But that this folly doubts it.”

“Where love is great, the littlest doubts are fear; Where little fears grow great, great love grows there.”

“Why, why is this?Think'st thou I'ld make a lie of jealousy,To follow still the changes of the moonWith fresh suspicions? No; to be once in doubtIs once to be resolved: exchange me for a goat,When I shall turn the business of my soulTo such exsufflicate and blown surmises,Matching thy inference. 'Tis not to make me jealousTo say my wife is fair, feeds well, loves company,Is free of speech, sings, plays and dances well;Where virtue is, these are more virtuous:Nor from mine own weak merits will I drawThe smallest fear or doubt of her revolt;For she had eyes, and chose me. No, Iago;I'll see before I doubt; when I doubt, prove;And on the proof, there is no more but this,--Away at once with love or jealousy!”

“O, beware, my lord, of jealousy;It is the green-ey'd monster, which doth mockThe meat it feeds on. That cuckold lives in bliss,Who, certain of his fate, loves not his wronger:But O, what damnèd minutes tells he o'erWho dotes, yet doubts, suspects, yet strongly loves!”

“Tis safter to be that which we destroyThan by destruction dwell in doubtful joy.”
