You never really answered my question about how we know what is absolute truth by way of observation and using our senses. I don't really want to talk about scientists or education or any of that sort, I just want to figure this out.
I'll use the example of consciousness. I advocate the idea of materialism, that is the mind (brain) causes our consciousness by means of neuronal firings etc, which you may or may not agree with, but by observation, when somebody gets hit in the head they become mentally impaired, their consciousness is effected.
There is a phenomenon called an OBE, out of body experience. This is when people believe they float above their body, their consciousness transcends their body and they can perceive the world around them. By observation alone, (if you experienced this) you would come to the conclusion you really transcended your body. Have you really transcended your body however? This a perfect example of the human senses can be extremely fallible.
If you subscribe to the idea of materialism like me, you should conclude that no, you cannot transcend your body it is merely a neurological hallucination. But going by senses alone one would believe they are capable of leaving their body at will.
So how do we go about deciding what is right and what is wrong? In this endeavour for truth, there needs to be some sort of system in place that will enable us to differentiate between the truth and illusions. We certainly cannot use our senses, the zetetic method is prone to unbelievable fallibility.
