America, it is said, is suffering from intolerance. It is not. It is suffering from tolerance: tolerance of right and wrong, truth and error, virtue and evil, Christ and chaos. Our country is not nearly so much overrun with the bigoted as it is overrun with the broad-minded. The man who can make up his mind in an orderly way, as a man might make up his bed, is called a bigot; but a man who cannot make up his mind, any more than he can make up for lost time, is called tolerant and broad-minded.
The nature of certain things is fixed, and none more so than the nature of truth. Truth may be contradicted a thousand times, but that only proves that it is strong enough to survive a thousand assaults. But for one to say, “Some say this, some say that, therefore there is no truth,” is about as logical as it would have been for Columbus, who heard some say, “The earth is round,” and others say, “The earth is flat,” to conclude: “Therefore there is no earth at all.”
Like a carpenter who might throw away his rule and use each beam as a measuring rod, so, too, those who have thrown away the standard of objective truth have nothing left with which to measure but the mental fashion of the moment.
