Captain Nemo pointed to this prodigious heap of shellfish, and I saw that these mines were genuinely inexhaustible, since nature's creative powers are greater than man's destructive instincts.

Nature's creative power is far beyond man's instinct of destruction.

Man is never perfect nor contented.

But to find, all at once, right before your eyes, that the impossible had been mysteriously achieved by man himself: this staggers the mind!

While there is life there is hope. I beg to assert...that as long as a man's heart beats, as long as a man's flesh quivers, I do not allow that a being gifted with thought and will can allow himself to despair.

Why lower oneself to taking pride from being American or British, when you can boast of being man!

What one man can think, another man can do.

In presence of Nature's grand convulsions man is powerless.

An energetic man will succeed where an indolent one would vegetate and inevitably perish.
