Shakespeare

"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?"

Merchant of Venice

"And therefore as a stranger give it welcome.
There are more things in heaven and earth, Horatio,
Than are dreamt of in your philosophy."

Hamlet

"O Romeo, Romeo, wherefore art thou Romeo?
Deny thy father and refuse thy name;
Or if thou wilt not, be but sworn my love
And I'll no longer be a Capulet"

Romeo and Juliet

"Love is not love
When it is mingled with regards that stand
Aloof from the entire point"

King Lear
