“An epiphenomenon is a collective and unitary-seeming outcome of many small, often invisible or unperceived, quite possibly utterly unsuspected, events. In other words, an epiphenomenon could be said to be a large-scale illusion created by the collusion of many small and indisputably non-illusory events.” —Douglas R. Hofstadter
