Uncertainty Quotes

“If it is true that an influx of doubt and uncertainty actually marks periods of healthy growth in a science, then evolutionary biology is flourishing today as it seldom has flourished in the past. For biologists collectively are less agreed upon the details of evolutionary mechanics than they were a scant decade ago. Superficially, it seems as if we know less about evolution than we did in 1959, the centennial year of Darwin's on the Origin of Species.”

“What held people together was the belief that you're really going to change the world. I think that's the nature of many startups. You believe that what you are doing is going to have a dramatic impact. You might not exactly know how, but you really have a belief. That keeps you going and going through many changes and a lot of uncertainty.”

“It might take us a lifetime to find out what it is we need to say. Most of us fall into where our feelings are headed while we're quite young. But the beauty of all this uncertainty would be that in the process of exhausting all the possibilities, we might actually stumble unconsciously into the recognition of something that's useful to us, that speaks to a deep need within ourselves. At the same time, I like to think that in order for any of us to really do anything new, we can't know exactly what it is we are doing.”

“This superficial blurring has something to do with the incapacity I have just mentioned. I can make no statement about reality clearer than my own relationship to reality; and this has a great deal to do with imprecision, uncertainty, transience, incompleteness, or whatever. But this doesn't explain the pictures. At best it explains what led to their being painted.”

“Physicists often quote from T. H. White's epic novel The Once and Future King, where a society of ants declares, "Everything not forbidden is compulsory." In other words, if there isn't a basic principle of physics forbidding time travel, then time travel is necessarily a physical possibility. (The reason for this is the uncertainty principle. Unless something is forbidden, quantum effects and fluctuations will eventually make it possible if we wait long enough. Thus, unless there is a law forbidding it, it will eventually occur.)”

“Now, since our condition accommodates things to itself, and transforms them according to itself, we no longer know things in their reality; for nothing comes to us that is not altered and falsified by our Senses. When the compass, the square, and the rule are untrue, all the calculations drawn from them, all the buildings erected by their measure, are of necessity also defective and out of plumb. The uncertainty of our senses renders uncertain everything that they produce.”
