My argument against the double-slit experiment in physics. look i agree with you but im using the term real as if real is variable and relative to our evolution. I totally believe there is an external world for which sense is in relation, but i dont think its real as in the universal concrete version chosen by abstract thought, which i believe has no special place, like we can ascertain a reality that is totally accurate universally simply because we use a culture of mathematics and experiment. the thing is you donĀ“t either, at present nobody does.
our senses are susceptible to illusion and ignorance, and so is our abstract world. but that is a good thing because the external world is always there, even though its changing, we can change with it and always keep our relation to it as close as possible.
usually when you give the argument people agree with you in essence but they still want to believe in the possible universal validity of their senses or abstract thought. they want this so bad because its a social value to be closest in the relationship to the external world, so the value real means that you are at that pinnacle of accuracy. but this drive to be accurate is always in danger of being mistaken to make the world we experience as the real one. or that science has achieved a universal perception that can clarify the senses and thought for eternity.
but what would happen if believing that we had finished the job has a negative effect on us for we have evolved to perceive a changing world and not a static one. so if science says we know whats going on maybe that degrades our relationship to the external world rather than enhancing it. that is the route and reason for my skepticism, not that i think we live in a dream.
