# Hard Problem of Consciousness > **Machine-Evolution Nexus:** [[articles/Digital Darwinism and the Invisible World of Machine Evolution|Digital Darwinism and the Invisible World of Machine Evolution]] provides the evolutionary and computational context for this supporting concept. **Domain:** Philosophy of Mind **Doc Type:** Supporting Canonical Node **Maturity:** Developed ## Definition The hard problem of consciousness asks why and how physical or computational processes are accompanied by subjective experience. David Chalmers distinguishes this from the “easy” problems of explaining cognitive functions such as discrimination, report, attention and behavioral control. Those functions may be scientifically formidable, but a functional account does not by itself explain why their performance is accompanied by experience. ## Nexus Context Digital evolution explains adaptive organization and heredity without answering why any resulting system would feel. This prevents evolutionary complexity from being misreported as consciousness evidence. ## Relationships [[wiki/Qualia|Qualia]] names the felt or phenomenal character at issue. [[wiki/David Chalmers|David Chalmers]] gives the problem its canonical modern formulation. Competing responses include physicalist reduction, illusionism, emergentism, dualist views and theories such as [[wiki/Integrated Information Theory|Integrated Information Theory]]; the existence of the problem does not select among them.

What kind of creatures are we? Are we composites of physical bodies and nonphysical experiences? Or are we entirely physical, or entirely nonphysical?

We cannot, for instance, answer the basic question: Why must this particular pattern of neural activity or this functional property cause, or be, this particular conscious experience (say, the smell of garlic) instead of that other conscious experience (say, the smell of a truffle), or instead of no conscious experience at all? Precise predictions of this type, de rigueur for genuine scientific explanations, have yet to be fashioned, or even plausibly sketched, with the standard tools.” > **— Donald D.

But it has not — at least so far — been because I learned any new facts. Contrary to the hopes of neuroscientists on one side, quantum physicists on the other, I'm pretty sure all the facts that we need to solve the hard problem are already familiar to us — if only we could see them for what they are. No magic bullet is going to emerge from the lab, from brain imaging or particle accelerators. Instead, what we are waiting for is merely (!) a revolutionary new way of thinking about things that we all, as conscious creatures, already know — perhaps a way of making those same facts unfamiliar.” > **— Nicholas Humphrey**, *2008, Edge Annual Question, “WHAT HAVE YOU CHANGED YOUR MIND ABOUT?
