Actually you did a pretty good job explaining it the first time. 100% logic, absolutely black and white.
I do think Michael has a point though. At our core, we are not logical thinkers, we are empiricists, inductivists. We think bottom up. "Hey, I saw 100 white swans and not a single black one. Therefore all swans must be white.". During our evolution we've rarely had the chance to truly deduce knowledge based on our observations, because the only logic thing you can deduce, is you cannot truly deduce anything valuable based on a finite set of observations. Therefore, survival of the fittest did not select for deductive reasoning and as such, it isn't part of our 'design'.
The real question is then, why can we do it after all? Is it a byproduct of our evolved intelligence, or am I wrong and was there a (or more) specific advantage of being able to make logical deductions?
Can you think of a situation, in which it would make a difference in our survival chances (or REDACTED reproduction), if we were able to make logical deductions? (aside from empiric inductions, which are in my opinion, never true deductions)
