Fortunately there is more to human reason than just logic.

Those surprised to read this statement from a student of logic ought to consider the following:

Imagine a gunman pointing his revolver at you.

Would you prefer to take the time to work out a syllogism as to why it would be advisable for you to duck?

Or would you, instead, prefer to allow instinct dictate your next action?

Logic is an excellent way to assess the proper courses of action, but it is not always the best way It is certainly not the quickest. Humans rely on other modes of 'decision making', including, but not limited to, instinct, emotion, and cognitive shortcuts such as heuristics or schemas.

Besides, non logical does not mean illogical!
