THE BELFAST ADDKESS. 153 



he simply meant to affirm men's differences to "be so 

 great, that what was subjectively true to the one might 

 be subjectively untrue to the other. The great Sophist 

 never meant to play fast and loose with the truth by 

 Baying that one of two opposite assertioDs, made by the

 his great scheme of the solar system. He made its 

 blocks eternal ; and even to those who feared it, and 

 desired its overthrow, it was so obviously strong, that 

 they refrained for a time from meddling with it. In 

 the last year of the life of Copernicus his book appeared :
