Othello (Act I sc iii) - Lago

IAGO-


It is merely a lust of the blood and a permission of
the will. Come, be a man. Drown thyself! drown
cats and blind puppies. I have professed me thy
friend and I confess me knit to thy deserving with
cables of perdurable toughness; I could never
better stead thee than now. Put money in thy
purse; follow thou the wars; defeat thy favour with
an usurped beard; I say, put money in thy purse. It
cannot be that Desdemona should long continue her
love to the Moor,-- put money in thy purse,--nor he
his to her: it was a violent commencement, and thou
shalt see an answerable sequestration:--put but
money in thy purse. These Moors are changeable in
their wills: fill thy purse with money:--the food
that to him now is as luscious as locusts, shall be
to him shortly as bitter as coloquintida. She must
change for youth: when she is sated with his body,
she will find the error of her choice: she must
have change, she must: therefore put money in thy
purse. If thou wilt needs damn thyself, do it a
more delicate way than drowning. Make all the money
thou canst: if sanctimony and a frail vow betwixt
an erring barbarian and a supersubtle Venetian not
too hard for my wits and all the tribe of hell, thou
shalt enjoy her; therefore make money. A pox of
drowning thyself! it is clean out of the way: seek
thou rather to be hanged in compassing thy joy than
to be drowned and go without her
