Love the horses, but don't ride on them! Riding the horses is a culture, a wrong culture!
Some boats are rotten in the ports; some boats shine in the hard journeys!
The roads to the stars are open only to those who grasp the great thoughts!
Wars can destroy everything but hope!
As long as you don't stop producing guns, you can't be a decent country!
Science is a seagull, it knows the sky; it is a squirrel, it knows the forest; it is a mole, it knows the underground; it is a dolphin, it knows the ocean! Science is a multi-talented creature!
