The contemptuous trap...........

“In general, the men of lower intelligence won out. Afraid of their own shortcomings and of the intelligence of their opponents, so that they would not lose out in reasoned argument or be taken by surprise by their quick-witted opponents, they boldly moved into action. Their enemies,on the contrary, contemptuous and confident in their ability to anticipate, thought there was no need to take by action what they could win by their brains.” 
-Thucydides
