This is one of the best descriptions for utopia I have come across. You may not be able to reach it–and it is good to know this–but it can certainly inspire movement, action, and lead at times to a better, even if not perfect, world.
She’s on the horizon… I go two steps, she moves two steps away. I walk ten steps and the horizon runs ten steps ahead. No matter how much I walk, I’ll never reach her. What good is utopia? That’s what: it’s good for walking. — Eduardo Galeano
