You are acutely conscious of yonder old monster when he is mouthing at you in politics.

Be wary of him in the heart; especially be wary of the disrelish of brainstuff.

You must feed on something.

Matter that is not nourishing to brains can help to constitute nothing but the bodies which are pitched on rubbish heaps.
Brainstuff is not lean stuff;--the brainstuff of fiction is internal history, and to suppose it dull is the profoundest of errors; how deep, you will understand when I tell you that it is the very football of the holiday-afternoon imps below.

They kick it for pastime; they are intelligences perverted.
