Ontological Commitment the human mind is so small that is forced to reduce reality down to abstract models, stories, maps, logics, etc....
the mind takes only the data that is required for our use and excludes the rest
this is what maps and stores and math etc... is. its an abstract reduction that is useable
words can point do actual sense data or to abstract mental things. as we communicate with other similar beings (humans) who share the same sense datas and or abstractions.
sense objects vs mental objects within total conscious reality
