1 " Criticism - however valid or intellectually engaging - tends to get in the way of a writer who has anything personal to say. A tightrope walker may require practice, but if he starts a theory of equilibrium he will lose grace (and probably fall off). "
― J.R.R. Tolkien , The Letters of J.R.R. Tolkien
2 " I think science works the way a tightrope walker works: by not looking at its feet. As soon as it looks at its feet, it realizes its operating in midair. "
― Annie Dillard , Living by Fiction
