@rabsinthe 'Irreducible ontology' just means cannot be explained by reference to more fundamental constituent things. The heart, for example, can be thought of as a pump and that fully explains what it does. Some people argue that the '#1stPersonOntology' of #consciousness is irreducible. Now, this may be true or false, but at the moment it is not explained. For myself, I can well imagine that it will be explained in the future and is therefore NOT #mysterian.
