“When liberty is mentioned, we must always be careful to observe whether it is not really the assertion of private interests which is thereby designated.”

“Pure mathematics consists entirely of assertions to the effect that, if such and such a proposition is true of anything, then such and such another proposition is true of that thing. It is essential not to discuss whether the first proposition is really true, and not to mention what the anything is, of which it is supposed to be true. [...] Thus mathematics may be defined as the subject in which we never know what we are talking about, nor whether what we are saying is true. People who have been puzzled by the beginnings of mathematics will, I hope, find comfort in this definition, and will probably agree that it is accurate.”

“Part of us is always the observer, and no matter what, it observes. It watches us. It does not care if we are happy or unhappy, if we are sick or well, if we live or die. It’s only job is to sit there on our shoulder and pass judgment on whether we are worthwhile human beings.”

“We are by nature observers, and thereby learners. That is our permanent state.”

“Interestingly one aspect of a designed tool is that it will inevitably be used in ways which were not anticipated by the designer.”

“Mounted on a horse, we were useful in direct proportion to our powers of observation and our ability to interpret what we say, faculties, of course, which are sharpened by interest. And our interest was boundless.”
