Logics handbook

[Rodion Romanovich]

a non-universal and minorative form of thinking

That sounds like they aren't using normal logic, or that they are misunderstanding logic. Logic states exactly the same as what everybody would say intuitively, but structures it up systematically to prevent fallacies when arguments get more complex. It isn't uncommon for people to either misunderstand logic or abuse the traps in it to deceive others while claiming to be using logic. Could you repeat what that person said so we can judge whether he was right or not?

Edit: actually originally logic stemmed from rather the opposite of what you describe. Read about Socrates, who tried to prevent being silenced by people with more power and influence, by demonstrating that what certain people trying to deceive stated could be nothing but lies. Socrates of course ended up killed for his sharp tongue and mind...
