How we cite our quotes: (Chapter.Paragraph)
Quote #4
"Who risks nothing gains nothing," said he. Ardan risked often and yet gained nothing. (18.41)
As you can already tell, Ardan doesn't look before he leaps. Strangely, this only makes us like him more—he's too busy enjoying his adventures to worry about a reward.
Quote #5
"Supposing that all the chances are in your favour, and admitting that you reach the moon - how will you return?"
"I will not return." (20.70-71)
Ardan doesn't care whether he lives or dies. To him, becoming the first human being to reach outer space is worth any cost. Plus, he can make a pretty good life for himself up there on the moon—we hear that selenite babes are fine.
Quote #6
"A man like Barbicane would not finesse with his enemy, nor lay traps, no practise any manoeuvre! He is too straight-forward, too courageous." (21.27)
Courage is the only thing that Barbicane and Ardan share in common. Both men pay the price for the fearlessness on more than one occasion, not least of which is the duel Barbicane is embroiled in here. That being said, this duel also teaches us that courage doesn't always lead to violence.
