Si peccasse negamus, fallimur, et nulla est in nobis veritas;

If we say that we have no sin, we deceive ourselves, and
there's no truth in us. Why, then, belike we must sin, and so
consequently die:
Ay, we must die an everlasting death.
What doctrine call you this, Che sera, sera,<19>
What will be, shall be? Divinity, adieu!
These metaphysics of magicians,
And necromantic books are heavenly;
Lines, circles, scenes,<20> letters, and characters;
Ay, these are those that Faustus most desires.
O, what a world of profit and delight,
Of power, of honour, of omnipotence,
Is promis'd to the studious artizan!
All things that move between the quiet poles
Shall be at my command: emperors and kings
Are but obeyed in their several provinces,
Nor can they raise the wind, or rend the clouds;
But his dominion that exceeds in this,
Stretcheth as far as doth the mind of man;
A sound magician is a mighty god:
Here, Faustus, tire<21> thy brains to gain a deity.

Enter WAGNER.<22>

Wagner, commend me to my dearest friends,
The German Valdes and Cornelius;
Request them earnestly to visit me.
