I certainly understand how Robert and Graham must feel when they are attacked by the orthos - I've experienced many of these kinds of attacks myself on this forum!
The problem is the orthos are "muscle-bound" by their intellects - they can't see the wood for the trees. This is the case because the intellect needs sham and tinsel to cover over its limitations, which would otherwise become plainly visible, it makes almost desperate efforts to look down on the simplicity of truth, which it fears will become a danger! It needs jingling bells for the cap it is wearing and many great words centred on it. But its contempt for the unvarnished simplicity of truth has long since turned to uneasiness! More and more bells are added to this gaudy fools cap which, through convulsive contortions and antics are made to jingle louder and louder in order to maintain itself for as long as possible on the usurped throne!
