why do we enjoy poetry From the perspective of neuroscience?

[Alan V]

What you aren't addressing are the important questions:
1)  If science is about observation, what observations do you make to establish whether a given system does/doesn't have a subjective experience of reality?

I already answered: a living body with an operational brain and nervous system.

2)  Why is there any such thing as subjective experience in a material monist reality, in which all process are mechanistic?

I already answered: because there is nothing external which can assure the survival of complex creatures, so they must be self-motivated -- which also requires subjective states as feedback.

You have said that awareness brings survival benefits.  If by awareness, you mean the ability to process and interact with the environment, so as to maintain viability long enough to reproduce, fine-- but an advanced machine could do that.  If by awareness, you mean the subjective knowledge of what things are like, then that is not really clear at all.

But what you are missing is that evolution could not have created such an advanced machine, because there is nothing in hostile or indifferent environments to do so. Only intelligent humans with their own motivations could, which is also why such a machine would never require consciousness. Programming imposed from without supplants the functions of evolved awareness.

I would like to add that your further question indicates that you are looking for reductionistic answers about consciousness. I think it is an emergent property, and is therefore not reducible to mechanistic physics. It depends, instead, on a very complex arrangement of materials -- without which it couldn't exist. This is why consciousness disappears with death. It doesn't split up into all the pieces of consciousness.
