# 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
