Final answer:
The writing of Common Sense was considered a revolutionary action at the time of the American colonies' struggle for independence from Great Britain. Thomas Paine's arguments fueled the desire for independence and contributed to the revolutionary cause, despite potentially being viewed as subversive by British authorities.
Step-by-step explanation:
The writing of Common Sense was considered a revolutionary action. This pamphlet, written by Thomas Paine, was a radical document at the time that made a compelling argument for the American colonies' independence from Great Britain. At a time when colonists were grappling with their relationship with Britain, the ideas in Common Sense galvanized many to the cause of independence, especially coming after events like the Prohibitory Act and the Battle of Bunker Hill which had already escalated tensions.
Treason, as defined in the Constitution, is much more specific and serious than simply writing inflammatory documents. It involves actions like levying war against the United States or aiding its enemies. Paine's pamphlet, while subversive and challenging to British authority, was primarily a call for action and enlightenment among the colonists, rather than a direct act of war or aid to enemies. Hence, while British authorities might have viewed it as subversive or even treasonous, in the context of the American Revolution, it was revolutionary.
