 Panpsychism has a long philosophical history (see the entry  panpsychism;  Skrbina 2005), but some find the doctrine incredible (Searle 1997; but see Chalmers 1997b; Alter and Nagasawa 2012: 90). Here it should be noted that Russellian panpsychists typically do not construe quiddities as macrophenomenal properties, that is, as familiar phenomenal properties such as those commonly associated with feeling pain and seeing red. More often, Russellian panpsychists construe quiddities as microphenomenal properties, that is, as phenomenal properties of microphysical entities. Microphenomenal properties might differ radically from the macrophenomenal sort (Chalmers 1996: 293–97; Strawson 2003, 2006a; Rosenberg 2004: 95). Some Russellian panpsychists construe quiddities as cosmophenomenal properties, that is, phenomenal properties of the whole cosmos, which might likewise differ radically from macrophenomenal properties (Goff 2017). So, the sorts of phenomenal properties that, according to Russellian panpsychism, underlie the most basic physical dispositions need not be much like any with which we are familiar. This might make panpsychism more palatable to some philosophers—though, some argue, if such properties differ enough from familiar macrophenomenal properties, one might doubt that they deserve to be called phenomenal at all (Kind 2006).
