>Regardless, my question is why did consciousness arise? What was the need? Think of it in terms of salience. Why do we need multiple levels of salience, such that some signals are intrinsically more important than others to the bearer of those signals? The answer is that once organisms were able to move under their own power, there needed to be a mechanism for the organism to have an intrinsic interest in its own well-being. A plant doesn't move under its own (intentional) power. It has no power to move itself into a damaging state nor move itself out of one. An intrinsic salience to its bodily integrity would serve no purpose. But once organisms were able to move based on goal-directed behavior, say to seek out food, it needs to have an interest in its bodily integrity such that it doesn't intentionally move into a damaging state. An intrinsic salience to nociceptive signals, i.e. the suffering of pain, gives organisms an innate interest in its bodily integrity. To evolve the same behavioral patterns without pain's intrinsic suffering quality would require evolving an organism that had an innate comprehension of why it is important to avoid damaging states, i.e. declarative representations of value which would require complex intelligence to co-evolve. Consciousness is the solution to the problem of competent behavior without comprehension.
