6 MAN'S ERROKS. 



26. The disavowal or non-admission of man's Unship to, 

 or fellowship with, other animals ; obliviousness of the fact 

 that they are fellow-creatures or fellow-mortals, with fellow-

 pre-eminence, for the vaunted dignity of human nature. 



10. The tendency to harsh or hasty judgments on the

11. The liability to morbid credulity or credulousness.
