People always get tired of one another. I grow tired of myself whenever I am left alone for ten minutes, and I am certain that I am fonder of myself than anyone can be of another person.
I was taught when I was young that if people would only love one another, all would be well with the world. I found when I tried to put that into practice, not only were other people seldom lovable but I wasn't very lovable myself.
In the Middle Ages people believed that the earth was flat, for which they had at least the evidence of their senses: we believe it to be round, not because as many as 1 percent of us could give physical reasons for so quaint a belief, but because modern science has convinced us that nothing that is obvious is true, and that everything that is magical, improbable, extraordinary, gigantic, microscopic, heartless, or outrageous is scientific.
I tell you that as long as I can conceive something better than myself I cannot be easy unless I am striving to bring it into existence or clearing the way for it.
