Achilles will not to the field tomorrow

Ulysses
Achilles will not to the field tomorrow.
Agamemnon
What's his excuse?
Ulysses
He doth rely on none,
But carries on the stream of his dispose,
Without observance or respect of any,
In will peculiar and in self-admission.
Agamemnon
Why, will he not, upon our fair request,
Untent his person and share th' air with us?
Ulysses
Things small as nothing, for request's sake only,
He makes important. Possessed he is with greatness
And speaks not to himself but with a pride
That quarrels at self-breath. Imagined worth
Holds in his blood such swoll'n and hot discourse
That ‘twixt his mental and his active parts
Kingdomed Achilles in commotion rages
And batters down himself. What should I say?
He is so plaguy proud that the death-tokens of it
Cry “No recovery.”
