What is logic?

[SuperSentient]

By looking at the title, I thought this thread would be more about discussing the nature of logic, but apparently not.

If you only would have analysed properly my sentence you would have understood that my explanation of logic go hand in hand with what most dictionaries say.

Take this explanation from one of the link from Thumpalumacus.
It say...........  a science that deals with the principles and criteria of validity of inference and demonstration.......and then about inference it say........... something that is inferred; especially :  a conclusion or opinion that is formed because of known facts or evidence........

Now read again my sentence in the OP.......it say..........Logic is when the feeling of satisfaction is permanent not temporary.

By bringing VALIDITY about known fact then I do fulfill the criteria of logic because it is a known fact that
material-physical things are unable to bring permanent satisfaction.
I do bring known facts that lead to conclusions therefore I follow logic.
All this should have rung a bell in your mind Atheo but if you think it didn't then you got a problem.  

Well, the definition you had in the OP is flawed, but I now see that you are trying to turn logic into some objective immaterial abstraction.
