People often heard the saying that the living could never compare to the dead. This was actually based on a very simple principle of psychology: the completion ability of Human Consciousness.
Some might have heard that the brain was a supercomputer beyond the reach of any machine, and its greatest strength lay in its ability to fill in gaps. You might think all the information you received was what you truly saw, but in fact, 15% or more of it was filled in by your own brain.
For example, unless you were Voldemort, you should be able to see your own nose. But think carefully about the first-person images in your memory—how many of them were blocked by your nose?
The blind spots in human vision were not limited to the nose. Much of the time, the information the eyes truly received was sparse, with most of it filled in by the brain. This was concrete completion, while human consciousness could perform abstract completion.
When describing something, mentally healthy people were inevitably logical. Cause and effect, for instance, was one of the simplest forms of logic.
Because someone wore too little clothing, he felt cold. This was the simplest cause-and-effect logic. But when thinking through it, consciousness helped fill in what had not been mentioned: he felt cold because he wore too little because the weather was cold. If the weather were warmer, then no matter how little he wore, he would not feel cold.
People instinctively assumed this logic took place on the premise that the weather was cold. So when replying, they naturally reminded him to wear more next time, or followed the thread into a discussion of the recent cooling trend. Every response arose from the foundation that "the weather is cold."
This was an underlying logic
