Consequently, studies of the brain have required many models and theories at many levels that involve disciplines from basic physics, to neurosciences, psychology and philosophy. For over 2000 years the two most controversial and unresolved models of brain phenomena involve what we call _free will_ and _consciousness_. I argue that adequate models at all levels require epistemic _complementarity_ – distinct necessary models that are not derivable or reducible to each other. The primitive irreducible complementarity at all levels is the _subject-object_ distinction required by an _epistemic cut_. This complementarity first arises with self-replication where a _self_, the _subject_, must be distinguished from the _non-self_, the _object_
