Final answer:
John Adams' statement implies that self-oppression can occur, which supports the need for constitutional safeguards and vigilant protection of liberties against abuses of power by the government.
Step-by-step explanation:
The passage from "A Defense of the Constitution" by John Adams implies that the author believes there are cases where self-oppression can occur. Adams appears to challenge the notion that people never oppress themselves, which suggests a more nuanced understanding of liberty and governance. Additionally, in the context of the broader writings and beliefs of the founding era, as reflected in the Declaration of Independence and influenced by thinkers like Thomas Jefferson, the ability for a government to become oppressive, even if it is of the people's own making, is recognized. This further establishes the need for constitutional safeguards and vigilance to maintain liberty and prevent despotism.
The idea that governments derive their power from the consent of the governed, as mentioned in multiple passages, underscores the belief that individuals have the right and duty to change or overthrow a government that becomes destructive to their unalienable rights. These foundational principles are part of a longstanding political philosophy that values personal liberty, participatory governance, and the necessity of protecting constitutional liberties against potential abuses of power.
