“By marrying experiment to speculation, we put ourselves in a dimmer version of the circumstance of the Creator. We remake nature or we imagine it remade. By this expedient we free ourselves, if only partly and tentatively, from suspicion of our beliefs, and we live once again, unafraid, in the light of the actual.”

Context: Do we find ourselves a species naturally free from conflict? We do not. There has not, apparently, been in our evolution a kind of rationalization which might seem a possible solution to problems of conflict--namely, a takeover by some major motive, such as the desire for future pleasure, which would automatically rule out all competing desires. Instead, what has developed is our intelligence. And this in some ways makes matters worse, since it shows us many desirable things that we would not otherwise have thought of, as well as the quite sufficient number we knew about for a start. In compensation, however, it does help us to arbitrate. Rules and principles, standards and ideals emerge as part of a priority system by which we guide ourselves through the jungle. They never make the job easy--desires that we put low on our priority system do not merely vanish--but they make it possible. And it is in working out these concepts more fully, in trying to extend their usefulness, that moral philosophy begins. Were there no conflict, it [moral philosophy] could never have arisen.

Tendemos a desconfiar increíblemente de nuestras percepciones cuando ya son pasado y no se ven confirmadas ni ratificadas desde fuera por nadie, renegamos de nuestra memoria a veces y acabamos por contarnos inexactas versiones de lo que presenciamos, no nos fiamos como testigos ni de nosotros mismos.

Context: In an age which no longer waits patiently through this life for the rewards of the next, it is a crushing spiritual blow to lose one's sense of participation in mankind's journey, and to see only a huge milling-around, a collective living-out of lives with no larger purpose than the days which each accumulates. When we estrange ourselves from history we do not enlarge, we diminish ourselves, even as individuals. We subtract from our lives one meaning which they do in fact possess, whether we recognize it or not. We cannot help living in history. We can only fail to be aware of it. If we are to meet, endure, and transcend the trials and defeats of the future — for trials and defeats there are certain to be — it can only be from a point of view which, seeing the future as part of the sweep of history, enables us to establish our place in that immense procession in which is incorporated whatever hope humankind may have.
