2* LIFE AND HABIT.

 times extends to positive disbelief in the thing known, 

 so that the most thorough knower shall believe him- 

 self altogether ignorant. No thief, for example, is such

 observed, it is rare to find any one strongly under this 

 impression without ourselves having good reason to 

 differ from him. 



Our own existence is another case in point. When 

 we have once become articulately conscious of existing, 

 it is an easy matter to begin doubting whether we
