Emergence
The way complex patterns, behaviors, or properties arise from the interaction of simpler parts that don't individually display those qualities — like how consciousness arises from neurons, or a murmuration from individual starlings.

Origin
The idea traces to Aristotle's observation that "the whole is greater than the sum of its parts." The modern philosophical term was introduced by George Henry Lewes in his 1875 Problems of Life and Mind, where he distinguished "emergent" effects from merely additive ones. The concept was revitalized in the late 20th century by complexity science and institutions like the Santa Fe Institute, founded in 1984.
