Was there to envy in the narrow bounds

Of Paradise, that spirits who pervade

Space——but I speak to thee of what thou know'st not,

With all thy Tree of Knowledge.

Cain.‍But thou canst not

Speak aught of Knowledge which I would not know,

And do not thirst to know, and bear a mind

To know.

Lucifer. And heart to look on?

Cain.‍Be it proved.
