The Collapse of Reason: Enlightenment Rationalism and the ‘Choice of Life’ in Johnson’s Rasselas
Introduction Samuel Johnson’s The History of Rasselas, Prince of Abissinia (1759) serves as a profound subversion of the optimistic rationalism characteristic of the eighteenth century. While the Enlightenment, championed by figures like Locke and Leibniz, posited that the application of human reason could decipher the laws of nature and lead to social perfection, Johnson’s narrative offers a counter-discourse. By situating the prince’s search for a “choice of life” within a landscape of perpetual disillusionment, Johnson argues that human reason is not a tool for achieving happiness, but a mirror reflecting the inherent “vanity of human wishes.” This paper analyzes how Johnson utilizes Rasselas’s journey to expose the limitations of Enlightenment rationalism, demonstrating that the pursuit of a definitive life-path is a structural impossibility.
The Failure of Empirical Methodology Rasselas’s project—to systematically evaluate different modes of existence—is fundamentally an empirical one. He approaches life as a laboratory, believing that if one gathers enough data points (the hermit, the scholar, the farmer), one can extrapolate a universal truth. However, Johnson utilizes the “conclusion in which nothing is concluded” to satirize this scientific approach. The prince fails because he treats the “choice of life” as an external problem to be solved through observation, ignoring the internal, chaotic nature of human desire. As Johnson posits:
“The heart of man is a repository of all that is false, all that is corrupt, and all that is fleeting” (Johnson 52).
By demonstrating that the prince’s empirical observations lead only to contradictory data, Johnson asserts that human happiness is not a variable that can be solved by the rational mind.
Reason as a Tool of Containment Within the narrative, the more the characters rely on their “reason,” the more trapped they become. The Astronomer, for instance, is the text’s most vivid emblem of rationalist hubris. He has spent decades mastering the heavens, yet his mastery has rendered him a prisoner of his own delusions. His “reasoning” has led him to the madness of believing he controls the weather. Here, Johnson suggests that Enlightenment rationalism, when decoupled from the humility of lived experience, inevitably curdles into monomania. The prince’s attempt to “reason” his way out of the Happy Valley is thus portrayed as a transition from a physical enclosure to an intellectual one, where the walls are built of one’s own rigid logic.
The Inadequacy of the “Choice of Life” The central conceit of the “choice of life” relies on the Enlightenment belief in human autonomy—the idea that the individual can shape their destiny through informed, rational selection. Johnson dismantles this by highlighting the role of contingency and external circumstance. No matter how rational the choice, life remains subject to death, illness, and the “misery of existence.” By refusing to allow Rasselas to find a “perfect” choice, Johnson aligns himself with a skeptical tradition that prioritizes endurance over improvement. The prince’s return to Abissinia is not a failure of character, but an acceptance of the limitations of the human condition.
The Prince: The Empirical Trap
Rasselas himself acts as the primary vehicle for the failure of Enlightenment methodology. He approaches the “choice of life” as a scientific experiment, believing that by traveling and observing, he can accumulate sufficient data to deduce the “best” way to live.
- Evidence: His journey to Cairo is a systematic sampling of lives. However, he discovers that the “life of the hermit” is solitary, the “life of the shepherd” is dull, and the “life of the wealthy” is filled with anxiety.
- Rationalist Failure: Rasselas’s rationalism fails because he assumes that happiness is a variable to be discovered in the environment. He is blinded by the Enlightenment fallacy that the world is a legible text that can be decoded by a systematic, reasoning mind.
The Astronomer: The Hubris of Reason
The Astronomer is perhaps the most devastating portrait of rationalist monomania in eighteenth-century literature. He represents the extreme end of Enlightenment inquiry, having mastered the most complex discipline of the age: the movements of the stars.
- Evidence: His expertise in mathematics and physics leads him to the belief that he has gained control over the natural world, eventually concluding that he is responsible for the regulation of the weather and the timing of the seasons.
- Rationalist Failure: Johnson shows that reason, when divorced from human interaction and communal reality, curdles into madness. The Astronomer is “the emblem of the rational mind in isolation.” His fall into delusion proves that pure reason, once stripped of external reality, creates its own internal—and often dangerous—logic.
Imlac: The Sage of Limits
Imlac serves as the voice of Johnson’s skeptical pragmatism. He is the most “enlightened” character, yet he is also the one who most frequently warns the others of the limitations of their rational quests.
- Evidence: Imlac explicitly tells Rasselas that the desire for a perfect “choice of life” is a form of vanity. He reminds the Prince that “human life is everywhere a state in which much is to be endured, and little to be enjoyed” (Johnson 48).
- Rationalist Failure: Imlac’s role is to act as the internal critic of the narrative. He represents the “enlightened skeptic” who realizes that the human condition is fundamentally resistant to the neat, categorized solutions proposed by early Enlightenment theorists.
The Hermit: The Miscalculation of Solitude
The Hermit represents the Enlightenment belief in “ascetic rationalism”—the idea that one can achieve wisdom by removing oneself from the “irrational” influence of society.
- Evidence: After living in isolation to pursue wisdom, the Hermit confesses to the Prince that he is miserable and yearns to return to the world of men.
- Rationalist Failure: His “choice” was perfectly logical on paper—remove all distractions to reach peace—but it failed to account for the fundamental human need for community. His retreat shows that rational planning cannot override the biological and social nature of human beings.
- Conclusion Johnson’s critique of Enlightenment rationalism in Rasselas is not an abandonment of the intellect, but a call for its proper orientation. He suggests that the “choice of life” is a false dichotomy between action and reflection, when in reality, the human subject is doomed to the frustration of both. In the context of the Delhi University syllabus, Rasselas stands as an essential text for understanding the transition from the exuberant confidence of the early Enlightenment to the skeptical introspection of the late eighteenth century. Johnson leaves the reader not with a formula for success, but with the sobering realization that human wisdom begins only when we stop trying to rationalize the irrational nature of our own existence.
In Samuel Johnson’s Rasselas, the breakdown of Enlightenment rationalism is not merely a thematic abstract; it is embodied in the specific, tragic trajectories of the characters themselves. Johnson uses his cast to demonstrate that whenever characters attempt to “choose” their life through pure, detached reason, they inevitably encounter the limits of human knowledge and the resurgence of irrational desire.
