A space of qualia is defined to be a sober topological space whose points are the qualia and whose open sets are the pure concepts in the sense of Lewis, carrying additional algebraic structure that conveys the conscious experience of subjective time and logical abstraction. This structure is analogous to that of a space of physical measurements. It is conjectured that qualia and measurements...
I propose that qualia are physical because they are directly observable, and revisit the contentious link between consciousness and quantum measurements from a new perspective -- one that does not rely on observers or wave function collapse but instead treats physical measurements as fundamental in a sense resonant with Wheeler's it-from-bit. Building on a mathematical definition of measurement...
