Charles Krauthammer writes a fine essay in defense of certainty. The heart, but by no means all, of his piece is here:
Well put. Krauthammer might also have mentioned that it's not really certainty that contemporary skeptics disdain, for they themselves are filled to overflowing with it. They are so certain that they are in the right politically, for example, that they are willing to go to any lengths to defame, discredit, mock and ridicule those with whom they disagree in order to crush all opposition and to insure that their views prevail. This is not the behavior of people cognizant of their own fallibility and at pains to maintain a modicum of intellectual humility.
No, it isn't certainty to which our Leftist elites object. What they find deplorable is the substance of those matters about which religious conservatives are certain. The maddening offense of religious conservatives is that their certitudes are in conflict with the certitudes of the secular Left. This the elite finds quite insufferable. They cannot abide that anyone would have the temerity to entertain a sense of certainty about matters so out of harmony with what they themselves are certain about.
