    # 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
