What Archimedes said of the mechanical powers, may be applied to Reason and Liberty. ‘Had we, ‘ said he, ‘a place to stand upon, we might raise the world.’The revolution of America presented in politics what was only theory in mechanics. So deeply rooted were all the governments of the old world, and so effectually had the tyranny and the antiquity of habit established itself over the mind, that no beginning could be made in Asia, Africa, or Europe, to reform the political condition of man. Freedom had been hunted round the globe; reason was considered as rebellion; and the slavery of fear had made men afraid to think.
