Is Aristotle's logic sufficient to model human reasoning?
If not, why not?
Are there counter-examples, certain cases where we reason differently?
Let's assume we're talking about sound reasoning, or the reasoning of the ideal human reasoner.
EDIT: I'm asking here about our decision-making procedure, not that part of human thought that has no need of logical systems. I should have been more specific and asked whether we need more thatthan the 'laws of thought' to perform our calculations in philosophy.
EDIT 2: I'm not asking about syllogisms. I'm asking about the essential logical rules that allow us to construct syllogisms and other arguments.
