Quotes from Will Durant - Ariel Durant

Man's ingenuity often overcomes geological handicaps: he can irrigate deserts and air-condition the Sahara; he can level or surmount mountains and terrace the hills with vines; he can build a floating city to cross the ocean, or gigantic birds to navigate the sky. But a tornado can ruin in an hour the city that took a century to build; an iceberg can overturn or bisect the floating palace and send a thousand merrymakers gurgling to the Great Certainty.
