"This is an extraordinary lapse of logic: a failure to distinguish between the means of observation, and the act of observation itself. The misleading use of the words "observe" and "measure" is to blame. Quantum states do not have indefinite values which become definite when they are measured---they have indefinite values which become definite when the quanta interact in certain ways with other quanta. The means of observation are these interactions, which are going on all the time whether we are watching or not: our observations depend on them, not vice-versa! Observation is secondary--not primary." I am new here, so bear with me if you will. When I started painting and dealing with oil colors, I believed that color was absolute, but artists would tell me that it is relative (subjective). My brain told me a subject was wearing a white shirt, thus I wanted to paint it white. My work suffered immensely because what an observer sees is almost everything but pure white yet Our indoctrination has informed our mind to judge it white. With my simple understanding of objectivism I recoiled that my senses could be deceived. However, this is my current understanding and it came to mind from the above quote from Victor. Color as we know it is a relationship subject to an interplay of several elements: The object observed, the observers eye and interpretation by his mind (some see red others blue), light and atmosphere between the object and observer. Sometimes (certain conditions, interplay) we may say the object is blue, then the light chances and now it is red, or in the case of a chameleon the object changes, or fog roll in and changes our observation, or we take a hit of acid and our interpretation changes. What does not change is the nature and identity of any of the elements interplaying. When quantum theory states that quanta change due to observation, perhaps they do. Does that change their nature? Does that mean that reality is subjective and not objective. I don't think so. To me that is like saying a red object nature is changed because through interplay with an observer it now measures blue. Certainly by our language of measurement it is now blue, but that just instructs us as to its nature. I certainly think that ones pre-disposition to philosophy influences many scientists pronouncements on the nature of the universe and nowhere as it does in Quantum Physics. A brilliant friend of mind PhD Nuclear Physicist turn Evangelical Preacher, gave up on science because Quantum Theory instructed him that Man really at the end of the day can know nothing, because the world is all a massive illusion wielded by the Master Magician. Again, please use patience with me if you can. I hope that this reply adds something useful to this discussion.
