He states that any other methods of changing the Constitution would be "a dangerous expedient" and would risk "subverting the fundamental principles of the government." This suggests that he believes that making changes to the Constitution in ways other than through the established amendment process could result in negative consequences and potentially undermine the government's core principles.
