The scientific establishment has made a huge blunder by assuming that consciousness is a throw-off product of the physical brain. Scientists have been searching for those components of the brain that produce consciousness and have been unable to find them. This is because the brain does not produce consciousness.
In the past there was no organized attempt to investigate consciousness because those in orthodox scientific circles within the establishment had already decided that it wasn’t all that significant. However, in the past 20 years neuroscientist have been attempting to understand what it is, but have been unable to come to any kind of consensus.
Science is reductionist, which means scientific methods break systems down to understand their parts. However, consciousness is the most fundamental of all phenomena and can’t be broken down.
