Question

Which underlying theme of the work is evident in the passage?

Answer 1

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:

Answer 2

Possibly be struggle for self control or more the human desire to control the world?

Answer 3

The line, "O, what a world of profit and delight", hints that the speaker wants more power, through the words "profit" and "delight".
The line, "All things that move between the quiet poles
Shall be at my command: emperors and kings", hints the speaker's immense want for power.
