edu-details-x-hero.png

In this module, we examine tranquility as a moral discipline within the Founders’ understanding of the pursuit of happiness, tracing its development in the long friendship between John Adams and Thomas Jefferson. Their estrangement and eventual reconciliation reveal that happiness, in their view, required more than achievement or acclaim; it depended on the difficult work of ordering one’s passions, gaining perspective, and extending forgiveness.

Tranquility is not passive calm but hard-earned equilibrium, cultivated through reflection, humility, perspective, and ongoing practice. By examining their correspondence and shared philosophical insights, students will see how tranquility serves as a vital part of the pursuit of happiness as understood by the Founders.

Healing a Founding Friendship

Grounded in History

In this video, you will observe how the long public disagreements between John Adams and Thomas Jefferson gradually give way to a renewed friendship grounded in shared philosophical reflection. Watch for how their letters reveal tranquility not as mere calm, but as a practiced virtue shaped by forgiveness, restraint, daily discipline, and the steady ordering of the passions.

Tranquility as a Virtue in Adams and Jefferson’s Friendship

Focus on how tranquility is introduced as a virtue through the story of Adams and Jefferson’s political rivalry and eventual reconciliation. Think about what challenges their friendship faced and what tranquility might mean in this context.

Tranquility Under Pressure in Later Years

Consider how the ideal of tranquility was tested in the later years of John Adams and Thomas Jefferson. Both men experienced political disappointment, sectional strain over slavery, and the burdens of retirement from public life. Adams endured deep personal losses, including the death of Abigail Adams in 1818, while Jefferson struggled with financial stress and the contradictions within his own legacy. Reflect on how these pressures tested their ability to sustain equilibrium of the passions.

For both, tranquility was not a fleeting mood but a condition achieved through discipline. It required daily habits of reading, exercise, correspondence, benevolence, and the contraction of excessive desire. Their letters show that reflection on grief, patience in disappointment, and attention to present duties were essential to preserving peace of mind.

At the same time, their lives reveal both the limits and the resilience of this virtue. Adams grew skeptical about human perfectibility, and Jefferson placed enduring hope in education and the progress of reason. Yet both maintained that happiness depended upon cultivating inner steadiness despite outward uncertainty. In this way, their exchange demonstrates how tranquility could be pursued, imperfectly but persistently, even amid loss, doubt, and the unfinished American experiment.

Through reflection, moderation of the passions, daily discipline, and charitable exchange, they came to understand tranquility not as simple calm, but as equilibrium of a well-governed mind.

Their letters show that happiness required more than public achievement. It depended on virtuous habits, contraction of excess desire, patience in loss, and the steady practice of self-government. Their lifelong dialogue demonstrates that the pursuit of happiness rests on cultivating inner balance amid disagreement, disappointment, and change.
