There is an interesting essay by Anil K Seth in aeon concerning consciousness. I'll add one quote here but the whole thing is well worth reading because it raises some fascinating questions.
Consciousness is informative in the sense that every experience is different from every other experience you have ever had, or ever could have. Looking past the desk in front of me through the window beyond, I have never before experienced precisely this configuration of coffee cups, computers and clouds – an experience that is even more distinctive when combined with all the other perceptions, emotions and thoughts simultaneously present. Every conscious experience involves a very large reduction of uncertainty – at any time, we have one experience out of vastly many possible experiences – and reduction of uncertainty is what mathematically we mean by ‘information’.
Consciousness is integrated in the sense that every conscious experience appears as a unified scene. We do not experience colours separately from their shapes, nor objects independently of their background. The many different elements of my conscious experience right now – computers and coffee cups, as well as the gentle sounds of Bach and my worries about what to write next – seem tied together in a deep way, as aspects of a single encompassing state of consciousness.
A very large reduction of uncertainty is another aspect of Karl Friston’s idea that we navigate through life by avoiding surprises. Looking at it more widely, it also seems to be one of the great divides. Some people are pragmatic enough to understand how embracing uncertainty can be the best route to greater certainty. It is not even a paradox because we can be certain that something is uncertain.
Others seem to need the more immediate and lasting certainties of ideology and dogma, even at the expense of honesty, personal integrity and even outright silliness. Fake news propaganda is itself a dishonest evasion of a much deeper problem that is fake certainty.
