G. K. Chesterton Quote
But those dealing in the actual manufacture of mind are dealing in a very explosive material. The material is not merely the clay of which man is master, but the truths or semblances of truth which have a certain mastery over man. The material is explosive because it must be taken seriously. The men writing books really are throwing bombs.
