Knowledge is the eye of desire and can become the pilot of the soul. — Will Durant
The Enlightening Power of Knowledge
Will Durant’s observation positions knowledge as more than information—he sees it as the force that illuminates our deepest longings. Desire without knowledge can be blind or misguided, like a traveler lost in darkness. Yet, with the light of understanding, we are able to clearly see the objects of our yearning and pursue them wisely. This sentiment echoes throughout history, aligning with Socrates’ insistence in Plato’s dialogues that true fulfillment arises when one examines and understands one’s own desires.
Desire Transformed Through Understanding
Building on this, knowledge acts as the 'eye'—the discerning lens—through which desire is clarified and refined. When our ambitions are informed by insight, we no longer chase fleeting whims but pursue goals with intention and awareness. For example, Leonardo da Vinci’s passionate curiosity fueled not only his art but also his scientific investigations; knowledge elevated his desires, transforming them into achievements that bridged both creativity and reason.
From Vision to Navigation: The Pilot Metaphor
Durant’s metaphor takes flight as he describes knowledge as the soul’s pilot. While desire might set our direction, it is knowledge that steers us amidst life’s uncertainties. Homer’s 'Odyssey' offers a vivid illustration: Odysseus’ longing to return home is constant, but it is his cunning—born of knowledge—that enables him to navigate challenges and ultimately fulfill his quest. In this way, desire gives the journey purpose, while knowledge ensures progress and safety.
Moral and Philosophical Implications
The intertwining of knowledge and desire raises important philosophical questions about morality. As Durant, a historian and philosopher, often explored, raw desire can lead to chaos or harm if unchecked by understanding. Enlightenment thinkers like Immanuel Kant argued that reason should govern inclination, ensuring that desires are aligned with moral duty. Thus, by letting knowledge pilot the soul, individuals cultivate not only effectiveness but ethical integrity.
Guiding the Modern Human Experience
In our contemporary world, Durant’s insight remains profoundly relevant. The information-rich landscape empowers anyone to turn curiosity into expertise and aspiration into meaningful action. Countless innovators—such as Nobel laureate Marie Curie—show how focused knowledge channels desire into discoveries that benefit humanity. Ultimately, Durant invites us to let knowledge guide our passions, ensuring both personal fulfillment and communal progress.
