# 1999/4/30 #=============# # truth model # #=============# # Terminology: # Using what seem to be fairly standard terms, # and filling in some missing terms, # my basic model is: percept := man do perceive (existent) concept := man do conceive (percept) proposition := man do propose (concept) # combining these three actions (see NOTE below) proposition := man do recognize (existent) proposition means existent proposition is either truth or fiction # examining evidence and making logical inferences evidence := man do reduce (proposition) decision := man do integrate (proposition, evidence, all knowledge) decision is either man do know (proposition) or man do believe (proposition) or ... # Rand's definition of truth (IOE, page 48) is: # Truth is the product of the recognition # (i.e., the identification) of the facts of reality. truth := man do identify (facts of reality) # where identify is correct recognize man do know (truth) Example: LaLaLand NOTE: I think that our brains have adaptive networks which interconnect these three actions so that the resulting action proposition := man do recognize (existent) actually produces "perceptual judgments" (see David Kelley, "Evidence of the Senses") such as entity:1 isa concept:2 entity:1 has attribute:2 entity:1 do action:2 entity:1 isin relationship:2
