Advances in science won’t help us understand consciousness

Why science itself is part of the problem

The hard problem of consciousness is not a just little local difficulty that will be solved by advances in neuroscience. As Thomas Nagel said, ‘it invades our understanding of the entire cosmos and its history’. 

It was David Chalmers who first proposed a distinction between ‘hard’ and ‘easy’ problems of consciousness – a distinction which has been problematic ever since. It gives too much ground to those who believe neural and computational science explain consciousness key aspects of consciousness. And it is biased towards the perspective that there are parts of the mind that entirely belong to the physical world and are no more than physical way stations in the causal chain between sensory inputs and behavioural outputs.

Contrary to Chalmers, the hard problems of consciousness,  that will always resist understanding through objective quantitative investigations, go beyond subjective experience and ‘what it is like’ to be a conscious subject. They encompass  aspects of the mind that Chalmers categorises as ‘easy’.  These include:  our ability to describe our mental states, to focus our attention or deliberately to control our behaviour, and to acquire and integrate information; the difference between wakefulness and sleep; the degrees and content of consciousness. Moreover agency, selfhood, intelligence, and our relationship to time are also ‘hard’ in Chalmers’ sense. 

These aspects of consciousness are a measure of the distance between human beings and the rest of nature as it is seen through the lens of physical sciences. There are many reasons why natural science fails to capture them, and why this will not be a temporary state of affairs. Two reasons are particularly important. 

The first is that scientific enquiry is conducted by conscious subjects. Such subjects are prior to and presupposed in science. One wouldn’t therefore expect them to be accommodated in its theories. Albert Einstein, a profound philosopher as well as one of the greatest scientists who ever lived, appreciated this. In an interview, he makes the radical claim that measurement, the very essence of science, does not fit into relativity theory:
