ourselves whether all forms of optimism, even 

 though digestive or emotional in their origin, are 

 not in some measure their own justification; and 

 while attempting to discount the bias of health 

 towards "looking on the bright side of things," 

 we must inquire into the truth of such sayings as 

 that "the darkest hour conies before the dawn," 

 and that "when things are at their worst they 

 begin to mend." Last we must ask whether the 

 true rational optimism is, not "whatever is, is 

 right" but "whatever is wrong may be righted."
