Knowledge Refinement Quotes

Science is a self-correcting discipline that can, in subsequent generations, show that previous ideas were not correct.

Ideas improve. The meaning of words participates in the improvement. Plagiarism is necessary. Progress implies it. It embraces an author's phrase, makes use of his expressions, erases a false idea, and replaces it with the right idea.

Ideas are invented only as correctives to the past. Through repeated rectification of this kind one may hope to disengage an idea that is valid.

We do not progress from error to truth, but from truth to truth

Science is perhaps the only human activity in which errors are systematically criticized and, in time, corrected.

Knowledge is now accepted as the best we humans can do at the moment, but with the hope that we will turn out to be wrong - and thus to advance our knowledge. What's happening to networked knowledge seems to make it much closer to the scientific idea of what knowledge is.

Science starts with preconception, with the common culture, and with common sense. It moves on to observation, is marked by the discovery of paradox, and is then concerned with the correction of preconception. It moves then to use these corrections for the designing of further observation and for more refined experiment. And as it moves along this course the nature of the evidence and experience that nourish it becomes more and more unfamiliar; it is not just the language that is strange [to common culture].

Progress in science is often built on wrong theories that are later corrected. It is better to be wrong than to be vague.

It science involves an intelligent and persistent endeavor to revise current beliefs so as to weed out what is erroneous, to add to their accuracy, and, above all, to give them such shape that the dependencies of the various facts upon one another may be as obvious as possible.

But part of the job of economics is weeding out errors. That is much harder than making them, but also more fun.

In the evolution of knowledge-mistaken and unnecessary beliefs are forced out and supplanted by truer and more necessary knowledge. So too in the evolution of feelings, which takes place by means of art. Lower feelings-less kind and less needed for the good of humanity-are forced out and replaced by kinder feelings which better serve us individually and collectively. This is the purpose of art.

How thoroughly it is ingrained in mathematical science that every real advance goes hand in hand with the invention of sharper tools and simpler methods which, at the same time, assist in understanding earlier theories and in casting aside some more complicated developments.

To kill an error is as good a service as, and sometimes even better than, the establishing of a new truth or fact.

Most students of nature sooner or later pass through a process of writing off a large percentage of their supposed capital of knowledge as a merely illusory asset. As we trace more accurately certain familiar sequences of phenomena we begin to realize how closely these sequences, or laws , as we call them, are hemmed round by still other laws of which we can form no notion. With myself this writing off of illusory assets has gone rather far and the cobweb of supposed knowledge has been pinched (as some one has phrased) into a particularly small pill.

My job is to explain stuff you don't know or already know and have to unlearn. My job is to teach you stuff you don't know that you need to know, stuff you should know. I'm going to take what you already know and re-describe it.
