Shakespeare gives Shylock one of the most eloquent speeches in the Merchant of Venice:
Hath not a Jew eyes? Hath not a Jew hands, organs,
dimensions, senses, affections, passions; fed with
the same food, hurt with the same weapons, subject
to the same diseases, heal'd by the same means,
warm'd and cool'd by the same winter and summer
as a Christian is? If you prick us, do we not bleed?
If you tickle us, do we not laugh? If you poison us,
do we not die? And if you wrong us, shall we not revenge?
If we are like you in the rest, we will resemble you in that.
If a Jew wrong a Christian, what is his humility?
Revenge. If a Christian wrong a Jew, what should his
sufferance be by Christian example? Why, revenge.
The villainy you teach me, I will execute,
and it shall go hard but I will better the instruction.
(Act III, scene I)
