- Similarly, magic suggested there were unseen metaphysical worlds that existed and could be explored with the right knowledge. Both rocketry and magic were rebellions against the very limits of human existence; in striving for one challenge he could not help but strive for the other.

Did hear a challenge urg'd more modestly,
Unless a brother should a brother dare
To gentle exercise and proof of arms.
