The Genesis of Transgression: Desire as the Cause of Sin
The question of sin's origin has plagued philosophers and theologians for millennia, yet a recurrent theme emerges across the Great Books of the Western World: desire often stands as the fundamental cause. This isn't to condemn desire in its entirety, for desire is a natural and often necessary impulse for life and growth. Rather, it is the disordered or misdirected desire, unchecked by reason and unguided by a righteous will, that leads humanity down the path of transgression. From the ancient Greeks' emphasis on self-mastery to the Christian understanding of original sin, the narrative remains consistent: sin is often born from the heart's yearning for what is illicit, excessive, or simply out of alignment with a higher good.
Unpacking Desire: A Dual Nature
To understand how desire becomes the precursor to sin, we must first distinguish between its inherent nature and its potential for corruption.
- Natural Desire: Many philosophers, including Aristotle, recognized natural appetites and desires as essential for human flourishing. The desire for food, shelter, knowledge, or companionship are not inherently bad; they are drives towards genuine goods. Plato, in his Republic, illustrates the soul as a charioteer (reason) guiding two horses: one noble (spirit/thumos) and one unruly (appetite/epithymia). The appetitive part, driven by desires, is necessary but must be governed.
- Disordered Desire: Sin arises when these natural desires become inordinate, seeking inappropriate objects, or seeking appropriate objects in an inappropriate manner or degree. It is a turning away from a higher, more enduring good towards a lesser, fleeting one. This misdirection is where the problem truly begins.
The Crucial Role of the Will: When Desire Becomes Sin
It is not merely the presence of a desire that constitutes sin, but the will's assent to it. This distinction is paramount in the philosophical tradition, particularly within Christian thought.
Augustine on the Evil Will
St. Augustine, in his Confessions and City of God, powerfully articulates this relationship. For Augustine, sin is not a substance but a privation, a lack of good, and ultimately, a willful turning away from God, the supreme Good. His famous pear tree anecdote illustrates a sin committed "for the sheer love of sinning." Here, the desire wasn't for the pears themselves (a natural desire for food), but for the illicit act, for asserting one's own will against a perceived prohibition.
Augustine's key insight:
- Desire as Temptation: A desire might present itself as a temptation, but it only becomes sin when the will consents.
- The Malus Voluntas: The "evil will" (malus voluntas) is the true root. It is the deliberate choice to embrace a lower good in defiance of a higher one, or to simply choose disorder over order.
Aquinas and the Inordinate Appetite
St. Thomas Aquinas, building upon Aristotle and Augustine, further refines this understanding. He differentiates between the concupiscible appetite (desire for pleasure, avoidance of pain) and the irascible appetite (desire for difficult goods, avoidance of difficult evils). These appetites are natural, but they become sources of sin when they are inordinate – when they go against the dictates of right reason and divine law.
| Element | Description | Relation to Sin |
|---|---|---|
| Desire | A natural inclination or appetite towards a perceived good. | Can be good or neutral; becomes problematic when disordered or excessive. |
| Reason | The faculty of discerning truth, good, and moral law. | Should guide and temper desire; failure to do so allows desire to run wild. |
| Will | The faculty of choice, directing one's actions based on reason and desire. | The ultimate cause of sin when it assents to disordered desire, despite reason. |
| Sin | A deliberate act against reason and divine law, a turning from God. | The outcome of disordered desire combined with a consenting, misguided will. |
The will acts as the crucial intermediary. It is the power to choose whether to follow a desire, how to pursue it, and what end to direct it towards. When the will is corrupted or weak, it succumbs to the allure of disordered desires, making them the direct cause of sinful acts.

One path is lush and tempting, leading towards figures reveling in pleasure and earthly delights, while the other is steep and arduous, leading towards a distant, serene temple or intellectual pursuit, symbolizing the choice between vice and virtue, or disordered desire and rational will.)
Philosophical Perspectives on the Corrupting Impulse
Across the philosophical landscape of the Great Books, the theme of desire's complicity in sin is pervasive:
- Plato's Phaedrus: The unruly horse of appetite, if not properly guided by the charioteer (reason), leads the soul astray, preventing it from ascending to the realm of Forms. Sin, in this context, is a failure of self-governance and an indulgence in lower, fleeting pleasures.
- Aristotle's Nicomachean Ethics: While not speaking of "sin" in a theological sense, Aristotle discusses akrasia (incontinence or weakness of will), where one knows the good but acts against it due to overwhelming desire. This demonstrates the power of unchecked desires to override rational judgment, leading to moral failings.
- Stoicism (e.g., Epictetus, Marcus Aurelius): Emphasizes the control over one's passions and desires (apathia) as essential for virtue and tranquility. Allowing external events or internal desires to dictate one's state is seen as a fundamental error, a deviation from rational living.
In essence, these thinkers reveal that while desire itself is an intrinsic part of the human condition, it becomes the cause of sin when it overpowers reason and corrupts the will. The struggle against sin, therefore, is often a struggle for self-mastery, for aligning our deepest yearnings with truth, virtue, and the highest good.
