No More Learning

From both, my lord. Bellario greets your Grace.
[Presents a letter]
BASSANIO. Why dost thou whet thy knife so earnestly?
SHYLOCK. To cut the forfeiture from that bankrupt there.
GRATIANO. Not on thy sole, but on thy soul, harsh Jew,
Thou mak'st thy knife keen; but no metal can,
No, not the hangman's axe, bear half the keenness
Of thy sharp envy. Can no prayers pierce thee?
SHYLOCK. No, none that thou hast wit enough to make.
GRATIANO. O, be thou damn'd, inexecrable dog!
And for thy life let justice be accus'd.
Thou almost mak'st me waver in my faith,
To hold opinion with Pythagoras
That souls of animals infuse themselves
Into the trunks of men.
Thy currish spirit
Govern'd a wolf who, hang'd for human slaughter,
Even from the gallows did his fell soul fleet,
And, whilst thou layest in thy unhallowed dam,
Infus'd itself in thee; for thy desires
Are wolfish, bloody, starv'd and ravenous.
SHYLOCK. Till thou canst rail the seal from off my bond,
Thou but offend'st thy lungs to speak so loud;
Repair thy wit, good youth, or it will fall
To cureless ruin. I stand here for law.
DUKE OF VENICE. This letter from Bellario doth commend
A young and learned doctor to our court.
Where is he?
NERISSA. He attendeth here hard by
To know your answer, whether you'll admit him.
DUKE OF VENICE. With all my heart. Some three or four of you
Go give him courteous conduct to this place.
Meantime, the court shall hear Bellario's letter.
CLERK. [Reads] 'Your Grace shall understand that at the receipt
of your letter I am very sick; but in the instant that your
messenger came, in loving visitation was with me a young doctor
of Rome- his name is Balthazar. I acquainted him with the cause
in controversy between the Jew and Antonio the merchant; we
turn'd o'er many books together; he is furnished with my opinion
which, bettered with his own learning-the greatness whereof I
cannot enough commend- comes with him at my importunity to fill
up your Grace's request in my stead.
