Disbelief is a most useful servant for the glib and shallow soul who might like to impress with the fancy of his sober incredulity. Anyone – even a fool – might discern the obvious, and for want that he be taken as a sage seeing beyond common sight, and for want moreover that his thoughts remain unprovoked by sense, a man may shut off his sight, and set himself immodesty to decrying as myths all threats to his repose. This is the aspect of false scepticism which T.H. Huxley noted:
When I say that Descartes commemorated doubt, you must remember that it was that sort of doubt which Goethe has called ‘the active scepticism, whose whole aim is to conquer itself’; and not the other sort which is born of flippancy and ignorance, and whose aim is only to perpetuate itself, as an excuse for idleness and indifference. 
There is another aspect of false scepticism, however, noted by many, and to which G.C. Lichtenberg gave succinct expression:
With most people disbelief in one thing is founded on blind belief in another. 
Thereby a man might describe as a persistent myth any fact that stands against his beliefs. I suspect that this aspect largely underlies the other. Whatever the case, with both aspects in full play, we find that a mass of men sets about exploding “myths” all over the place, such that a dust and a general disorder is thrown up around every matter, to which it is then difficult to attract clear and calm attention.
