362 DIVERSIONS OF A NATURALIST 



a ghost, " There are more things in heaven and earth, 

 Horatio, than are dreamed of in your philosophy," are 

 gravely quoted as though they were applicable to the 

 Horatios of to-day. We have no reason to suppose 

 that there are more things in heaven and earth than are 

 dreamed of in our philosophy. Those who inappro- 

 priately quote this saying as though it were proverbial 

 wisdom are usually persons of very small knowledge, 

 and mistake their own limitations for those of mankind

 thing to explain or account for, not the marvel reported, 

 but the fact that certain persons say or are reported to 

 say that it does. What you have to examine, in the 

 absence of the marvel itself, is, " How is it that these 

 people make this statement ? " You must inquire into 

 the capacities and opportunities of the witnesses. There 

 are several possible and probable answers to that inquiry. 

 For instance, it may be that the witnesses are merely 

 inaccurate, or are self-deceived, or deceived by the 

 trickery or credulity of others, or are insane, or are
