I have been thinking about this today. I hope that it is not a Slipknot ( to quote the name of the metal band) of a question, or impossible to discuss. I have been thinking that it is the core question which goes beyond the dichotomies of metaphysics vs empiricism, religion vs science and determinism vs free will.

I won't try to offer any definitions of reality, simply because that would seem to defeat the purpose of my question. Of course, that doesn't mean that I am not wishing for people to look for definitions. I don't believe that the question of reality can be described in words easily, but I would not, in any way, be trying to suggest that it is ineffable. I think that this is a delicate juggling act in our thinking.

When I raise the issue of solidity, I am speaking about foundations and strengths and, of a capacity to stand firm and not be thrown asunder.I am asking about the solidity of the concepts which we have about reality, but also about the solidity of reality itself, especially in the light of the quantum world, as it is understood.

I hope that my question is not too vague to be seen as worth exploring, because I see it as central to all philosophical exploration.

Edit: I have changed title, to make it more a topic for philosophy reflection, because I was a bit surprised by how the topic was being explored. Of course, it may not alter any answer because the objective idea of reality may be the way you see it anyway.
