Of all beasts the man beast is the worst;
To others and himself the cruelest foe. 
-R. Bexter 
  
I’d be dog, a monkey, or a bear,
Or anything but that vain animal,
Who is so proud of being rational, 
-John Wilmot 
  
I sometimes think that God, in creating man, somewhat overestimated his ability. 
-Oscar Wilde. 

Man is the most intelligent of animals- and the most silly.
