Textbooks of biology repeat time and again that DNA is a 'blueprint' for building a body. It isn't. A true blueprint of, say, a car or a house embodies a one-toone mapping from paper to finished product. It follows from this that a blueprint is reversible. It is as easy to go from house to blueprint as the other way…
When we are asked to swear in courts of law that we will tell 'the truth, the whole truth, and nothing but the truth', we are being asked the impossible. It is simply beyond our powers. Our memories are fallible; even scientific truth is merely an approximation; and we are ignorant about nearly all of the Universe…
I think that science tolerates the unknown in a way that religion doesn't. My argument is not with people who search for god. My argument is with people who feel that our understanding of god is completed. And those are the people who make so much of our existence on this planet such a hell, because they really think…
I do not think that truth becomes more primitive if we pursue it to simpler facts. For no fact in the world is instant, infinitesimal and ultimate, a single mark. There are, I hold, no atomic facts. In the language of science, every fact is a field—a crisscross of implications, those that lead to it and those that…
Since then society has evolved a sequence of ci central con¬ cepts each of which was at one time thought to make it work of itself, and each of which has had to be corrected to the next. There was the early eighteenth-century concept of selfinterest, in Mandeville and others; then came enlightened self-interest; then…
All science, is the searchjnr njQJty in hidden likenesses. The search may be on a grand scale, as in the modern theories which try to link the fields of gravitation and electromagnetism. But we do not need to be browbeaten by the scale of science. There are discoveries to be made by snatching a small likeness from the…
This is, in fact the critical discovery of science. That we often perceive what we expect or want to perceive, often at variance with what is objectively true. The Cro Magnon genius of trumping objective evidence with subjective belief. The original and only true form of magic. How has science dealt with this…
Science seeks the truth. And it does not discriminate. For better or worse it finds things out. Science is humble. It knows what it knows and it knows what it doesn’t know. It bases its conclusions and beliefs on hard evidence -- evidence that is constantly updated and upgraded. It doesn’t get offended when new facts…
Since there is nothing to know about god, a comedian knows as much about god as any one else. An atheist however is alone in knowing that there is nothing to know so probably has the edge. An Atheist comedian can make people laugh about belief or lack of it. A good atheist comedian can make people laugh AND think…
Science doesn’t concern itself with the non-existence of something. The periodic table of imaginary things would be too big for a classroom- infinitely big in fact, and rather pointless. It’s not trying to prove the non-existence of anything supernatural. All it knows is there is no scientific proof of anything…
When I do long division or even multiplication I don’t try to remember the intermediate numbers. Long ago I learned to write them down. Because of paper and pencil I am “smarter” in arithmetic. In a similar manner I now no longer to try remember facts, or even where I found the facts. I have learned to summon them on…
What then is the meaning of the whole world? We do not know what the meaning of existence is. We say, as the result of studying all of the views that we have had before, we find that we do not know the meaning of existence; but in saying that we do knot know the meaning of existence, we have probably found the open…
Another key factor in assessing the trustworthiness of a document is the reliability or otherwise of the claims expressed within it; metadata about provenance will no doubt help in such judgements but need not necessarily resolve them. Representing confidence in reliability has always been difficult in epistemic…
There are two important epistemological questions for Web Science. The first is what properties will future platforms need to have in order to allow as much information as possible to gravitate to the Web without imposing structure or governing theories upon it? One aim of the Web is to facilitate rational discussion…
Could a man be placed in a situation, and endowed with power of vision to behold at one view, and to contemplate deliberately, the structure of the universe, to mark the movements of the several planets, the cause of their varying appearances, the unerring order in which they revolve, even to the remotest comet, their…
