“Physical vision - one might say scientific vision - brings about a metaphysical shift in the observer's view of reality as a whole. The geography of the earth, or the structure of the solar system, are in an instant utterly changed, and forever. The explorer, the scientific observer, the literary reader, experience the Sublime: a moment of revelation into the idea of the unbounded, the infinite.”

“Historically mystics have claimed that for a true understanding of reality metaphysics is too “scientific”. Metaphysics is not reality. Metaphysics is names about reality. Metaphysics is a restaurant where they give you a thirty-thousand-page menu and no food.”

“To produce a valuable observation, one has first to have an idea of what to observe, a preconception of what is possible. Scientific advances often come from uncovering a hitherto unseen aspect of things as a result, not so much of using new instruments, but rather of looking at objects from a different angle. This look is necessarily guided by a certain idea of what this so-called reality might be. It always involves a certain conception about the unknown, that is, about what lies beyond that which one has logical or experimental reasons to believe.”

“Making reality real is art's responsibility. It is a practical assignment, then, a self-assignment: to achieve, by a cultivated sensitivity for observing life, a capacity for receiving impressions, a lonely, unremitting, unaided, unaidable vision, and transferring this vision without distortion to it onto the pages of a novel, where, if the reader is so persuaded, it will turn into the reader's illusion.”

“The reality is that while heliocentrism was discussed and often accepted within Catholic circles - it was effectively the only place where it could be - the more traditional view of the solar system still prevailed even among leading scientists. So it's hardly surprising that Galileo's Catholic judges had difficulty accepting his views, especially when they saw themselves as defending scientific orthodoxy and were supported in this by the scientific establishment.”

“It is interesting that this thoroughness, which is a virtue, is often misunderstood. When someone says a thing has been done scientifically, often all he means is that it has been done thoroughly. I have heard people talk of the "scientific" extermination of the Jews in Germany. There was nothing scientific about it. It was only thorough. There was no question of making observations and then checking them in order to determine something. In that sense, there were "scientific" exterminations of people in Roman times and in other periods when science was not so far developed as it is today and not much attention was paid to observation. In such cases, people should say "thorough" or "thoroughgoing," instead of "scientific.”
