Extensional VS Intensional Logic

About: intensional logic (stanford encyclopedia of philosophy)



It’s the difference between bottom up rather than top down … inductive rather than deductive.  It is reasoning from example to thought, rather than from thought to example.   Instead of presuming that the language of our thoughts holds the truth of the matter,  we look at what actually is, external from our selves, and work backwards to how to think about it.

Abduction – the action or an instance of forcibly taking someone away against their will. Knowledge soup = ?
Is that something like word salad?  Looks like a block diagram rather than mentography IMHO.  It is more Ethos-Pathos than Logos. 
GW uses the word tzu to bridge logical gaps as in algebra ↔ geometry .

Actually a theory comes from observing the World & trying to explain its behavior. The World usually comes first. Only Goofball Warming enthusiasts invent the theory first. laughing

i think both things happen … bottum up → meets ← top down … somtimes we make an idea and manifest it or look for examples of it already being … other times we start from the opposite direction bottom up inductively.  which came first, the chicken or the egg,  i don’t think it matters.

Yep! Science or Science Fiction.  Who knows who cares? Same goes for politics, economics , sociology & education – the respect for the specific not withstanding.pondering

sounds like “rubber ducker sucker fucker” to me.   making up ideas and then manifesting them is not science fiction … nor is politics, economics, sociolody & education.   wel live in the NOW and we live in the specific … all glory in our minds notwistanding.
RWG getting obsessive – reason has left the building! Adios MF! tuitlater.
