Emergence: A consciousness cop-out?

Emergence: A consciousness cop-out?

Emergence is what I call a "black box" word. These words are used to make us believe we understand a phenominon simply by identifying it with a word. Other examles are "chaos," "comlexity" and "God." - JW

From consciousness to free will, and even life itself, it has become commonplace for philosophers and neuroscientists to explain some of the most puzzling phenomena in the universe as 'emergent'. Some even make the claim that nothing in science makes sense without emergence, the idea that the characteristics and behaviour of the whole is different from, and in addition to, its parts. But critics argue there is a danger emergence gives the impression of understanding when in reality it explains nothing.

Can we explain emergence and account for an overall property occurs when it is not present in the elemental parts? Might a new science of emergence enable breakthroughs in our understanding of life, consciousness and physical properties like superconductivity? Or is emergence a rhetorical device used to give the misleading impression that materialism is capable of explaining the deepest mysteries?
