Franklin's reference to the tower of babel is an allusion to a christian biblical reference. according to the reference, people wanted to build a great tower to reach the heavens, but their speech was changed so they could not talk to one another anymore. the people were scattered all over the world so they could no longer work together to complete the tower. practice what is franklin's purpose for using this allusion?

In his speech of June 28, 1787 in the Constitutional Convention, Franklins is making the case to build a united state with all the thirteen colonies. There had been long arguments of how to build the new states, where local interest prevailed over the attempt of building a single nation. They were failing in this political building as the builders of Babel had failed in their enterprise. It is the will of God to construct the new nation, and with their help they shall succeed. because the building of the United States would be the success of the building of a second Babel.

one of these is the rhoticity common in most american accents, because in the 17th century, when english was brought to the americas, most english in england was also rhotic.
