Bruno Latour and Elie During are going to exculpate Bergson and topple Einstein but in a way that will leave Einstein's 1905 false constant- speed-of-light postulate (the linchpin that holds Einsteiniana's money- spinner together) intact: http://footnotes2plato.com/2011/06/2...een-bergson-an... "Bruno Latour speaks above about how contemporary philosophy should re- interpret the verdict of the 1922 exchange between the metaphysician Henri Bergson and the physicist Albert Einstein. He finds a re- interpretation of this debate important especially in light of the new ecological constraints upon 21st century thinking. Traditionally, it is reported that Einstein won out over Bergson, dealing a swift scientific blow to the authority of philosophical intuition in cosmological discussions. Most came away from the exchange between these early 20th century thinkers of "time" believing that Bergson had been unveiled as a psychologist or an artist pretending to understand science. For Einstein, there is no such thing as "philosopher's time" - the living duration in which subject and object co-emerge, as Bergson might say; instead, Einstein marks two kinds of time: psychological time, which is a subjective illusion generated by relative motion, and physical time, which is objective reality existing eternally in the mind of God. He does exactly what Latour urges us not to: that is, he opposes theory to lived experience, the universal to the local. The asymmetrical time of conscious existence, where egg shells only shatter and never reassemble, is deemed by Einstein to be illusory. The flow of physical time is deemed reversible, no matter what the psyche seems to suggest about the steady aging of the body and the inevitable approach of death. From Einstein's geometer God's perspective, the regret of living bodies in response to their past, and the anxiety in the face of their future, is for naught: the truth is, the future has already taken place, and at no moment along the way did a "hesitation" or a "decision" ever occur. (...) A relevant paperhttp://stephenerobbins.com/talks/Relativity-philsci.pdf on Bergson's argument with Einstein concerning special relativity and perception." Pentcho Valev I looked at Bergson's paper. The problem with it is that he misses some of the predictions of Einstein's STR. If you understand STR properly, it is easy to resolve the barn door paradox. Also, if you understand that STR is not GTR, then you can resolve the twins paradox - either one of the twins is not in an inertial frame, and so STR doesn't apply to that twin's frame of reference, or gravity is involved, and that is beyond STR. But more than that, these paradoxes are so obvious that (a) either physicists the world over are utterly stupid, embracing non-reality, or pulling a deliberate hoax on the world, or (b) physicists really are smart, and they have thought about these apparent paradoxes, and have figured out the answer. I'll tell you this. When I started studying STR, at first I was convinced of (a). But after a few years of thinking about it - I mean really thinking about it, I realized that the answer was (b). Another thing - going to the source is not the best way to understand Einstein. Several times I have tried to understand him. Then I go away, and after much thinking I have a realization. And I think "why didn't Einstein say XXX?" Then I reread Einstein, and yes, he says "XXX" in the first paragraph. And I simply missed it. The guy really was smart. Very, very smart. And I don't say it out of any sense of hero worship. Rather it is because when I finally understand him, I realize how much faster he got it than I did. |
