Upon dissecting it we discover the "Modern Mind" to contain three main ingredients and to combine them through the force of one principle. Its three ingredients are pride, ignorance, and intellectual sloth; their unifying principle is blind acceptance of authority, not based on reason.
Pride causes those who suffer from this disease to regard whatever they think they have learned, whatever they have absorbed, through no matter how absurd a channel, as absolute and sufficient.
Ignorance forbids them to know with any thoroughness what men have discovered about these things in the past, and how certainly.
Intellectual sloth forbids them to examine an argument, or even to appreciate the implications of their own assertions.
With most men who are thus afflicted the thing is not so much a mixture of these vices as the mere following of a fashion; but these vices lie at the root of the mental process in question.
As to the principle of blindly accepting an authority not based on reason, it runs through the whole base affair and binds it into one: Fashion, Print, Iteration, are the commanders abjectly obeyed and trusted.
