“ All the universe is full of the lives of perfect creatures. ”
The world is desperately imperfect. Even if a quarter of the working people were engrossed in new thoughts and inventions and lived off the others, humanity would still gain tremendously thanks to the constant stream of inventions and intellectual work emerging from this horde of people striving upward.
~ Konstantin Tsiolkovsky
Earth is the cradle of humanity, but one cannot live in a cradle forever.
The Earth is the cradle of humanity, but mankind cannot stay in the cradle forever.
Man must at all costs overcome the Earth's gravity and have, in reserve, the space at least of the Solar System.
