former must produce a simple result, and then, if we 

 arrive at this simple result, the round number for 

 instance, it appears to us more reasonable to attribute 

 it to the simple cause, which was almost certain to 

 give it us, than to chance, which could only give it 

 us once in 10,000 times. It will not be the same 

 if we arrive at a result that is not simple. It is true 

 that chance also will not give it more than once in 

 10,000 times, but the simple cause has no greater 

 chance of producing it.
