The world is not something separate from you and me; the world, society, is the relationship that we establish or seek to establish between each other. So you and I are the problem, and not the world, because the world is the projection of ourselves, and to understand the world we must understand ourselves. That world is not separate from us; we are the world, and our problems are the world's problems.
In the scientific world I find just that disinterested devotion to great ends that I hope will spread at last through the entire range of human activity.
When a new truth enters the world, the first stage of reaction to it is ridicule, the second stage is violent opposition, and in the third stage, that truth comes to be regarded as self-evident.
The world is being created and destroyed in this very moment. Whoever you met will reappear, whoever you lost will return. Don’t betray the grace that was bestowed on you. Understand what is going on inside you and you will understand what is going on inside everyone else. Don’t imagine that I came to bring peace. I came with a sword.
Besides, in this random miscellaneous company we may rub against some complete stranger who will, with luck, turn into the best friend we have in the world.
