Final answer:
The Founding Fathers designed the Constitution to secure the blessings of liberty for themselves and their posterity, meaning all future generations.
Step-by-step explanation:
In devising the Constitution, the Founding Fathers sought to "secure the blessings of liberty to ourselves and our Posterity." The term 'posterity' refers to all future generations. The entire Constitution is drafted to create an enduring system of government, equipped with the tools needed to promote the ideals of liberty from the Founding Fathers to the current and future generations. This reflects the Founding Fathers' commitment not only to the people living during the establishment of the Constitution in 1787 but to all generations that would follow. Their vision was based on principles such as natural rights and a balance of power within the government, influenced by Enlightenment thinkers like John Locke and Montesquieu.
