 This is a philosophy of mind that regards the degrees of freedom between mental and physical well-being as not necessarily synonymous thus implying an experiential dualism between body and mind.An example of these disparate degrees of freedom is given by Allan Wallace who notes that it is "experientially apparent that one may be physically uncomfortable—for instance, while engaging in a strenuous physical workout—while mentally cheerful; conversely, one may be mentally distraught while experiencing physical comfort".Experiential dualism notes that our subjective experience of merely seeing something in the physical world seems qualitatively different than mental processes like grief that comes from losing a loved one.
