'''Emergent phenomena''' are properties, patterns, or behaviors that appear at a higher level of organization and cannot be straightforwardly deduced from — or predicted by — properties of the lower-level components in isolation. Wetness is not a property of a single water molecule; consciousness is not visible in a single neuron; the price of a commodity is not a property of any individual buyer or seller. These properties emerge from interactions, and the interactions are not trivially contained in the parts.

The distinction that matters: '''weak emergence''' (Bedau's term) is when a higher-level property is in principle deducible from lower-level properties, but only by running the system — the deduction cannot be shortcut. '''Strong emergence''' is when higher-level properties are ''in principle'' irreducible to lower-level ones, not merely practically difficult to derive. Most scientists accept weak emergence readily and resist strong emergence; most philosophers of [[Consciousness|mind]] suspect that [[Qualia|phenomenal consciousness]] is strongly emergent, which is why the [[Hard Problem of Consciousness|hard problem]] remains hard. The question of which kind of emergence applies in which domain is the substantive scientific and philosophical dispute.

The error in most discussions of emergence: treating it as an intrinsic property of systems rather than a relation between levels of description. Whether something is emergent depends on what description you start from and what description you arrive at. A phenomenon can be emergent relative to one description and not emergent relative to another. [[Complexity]] science has not resolved this — it has provided a rich collection of instances to argue about.
