Question

What are the key arguments that Thomas Jefferson makes for the colonies’ separation from Great Britain? In one paragraph please thanks.

Answer 1

For Jefferson, the basic elements of the argument for separation lie in a lack of respect.  Jefferson frames the argument that the violation of economic and political rights that the Colonists have had to suffer were the result of a lack of respect.  Jefferson is emphatic in how the British government has refused to "assent" to the basic principles of dignity and decency that could enable a successful relationship and partnership to develop.  For Jefferson, the critical argument that makes rebellion and dissolution absolute is that this lack of respect will not depart.  As long as this imbalance exists, the Colonists will be treated in a secondary manner, denying them their full voice and activation of their rights.  It is in this light where I think Jefferson's key arguments lie.  In the second section regarding the "Grievances" that the Colonists have borne, Jefferson outlines all that has been done.  In doing so, he solidifies his initial argument that separation from Great Britain is the only path that the Colonists can pursue.  The relationship between both nations has been so degraded by a lack of respect that there is no other option.
