Christ now shows them how they should have reasoned. Indeed he shows them the only way they could have reasoned, given the minds with which they had been furnished at their inception into the world.
The same is true of the influence the devil has on society. What uniformity we so often see in the thinking of the people of this world. Dissent is not tolerated, and enormous pressure is put on dissenters. People are afraid to step out of line, and the result is the farcical spectacle of everyone tipping their hat to the nonsensical meme that is in vogue at the current time.
