The Nature of Evil

Discussion Guide

The Section in One Sentence

Evil is not a rival creation but the corruption, absence, and distortion that appear when creatures depart from the source.

Key Concepts

Privatio boni — Evil as the privation (absence) of good, not a substance in its own right. Cold is not a thing; it is the absence of heat.
Evil as parasitic — Evil cannot exist on its own. It feeds on, distorts, and corrupts what is good. It has no independent creative power.
Incurvatus in se — Augustine's phrase: curved inward on oneself. The fundamental posture of the creature turned away from God and toward its own center.
Logoi / tropos — Maximus the Confessor's distinction between a thing's God-given purpose (logos) and the mode in which it actually exists (tropos). Evil is the gap between the two.
Void with gravity — The essay's image for evil's paradox: it is nothing (absence), yet it pulls. It has no being of its own, yet it exerts real force.

Scripture Anchors

Romans 1:25 — "They exchanged the truth about God for a lie, and worshiped and served created things rather than the Creator." The fundamental exchange: source for substitute.
Genesis 4 — Cain. The first murder as the fruit of the fall: envy, refusal, violence. Evil's trajectory from interior distortion to external act.
Revelation 12–13 — The dragon and the beast. Evil's cosmic register: organized, aggressive, mimicking divine authority. Parasitism at scale.

Discussion Questions

If evil is absence rather than substance, why does it feel so powerful? What does the "void with gravity" image add to the privation account?
What does it mean that evil can be "active and parasitic" at the same time? Can you name examples where something destructive was clearly feeding on something good?
How does Augustine's "curved inward" diagnosis match your experience? Where do you see incurvatus in se in ordinary life?
Maximus distinguishes between a thing's God-given purpose and its actual mode of existence. How does that distinction help you think about broken institutions, distorted desires, or corrupted goods?
Does the framework's account of evil leave anything important out? What would you want it to say that it doesn't?

Theological Notes

Tradition

Augustine (Confessions VII) — The classic articulation of privatio boni: evil is not a substance but a corruption of the good. Also the source of incurvatus in se, the soul curved inward on itself.
Gregory of Nyssa (Great Catechism) — Evil as departure from being. Since God alone truly is, movement away from God is movement toward non-being.
Athanasius (On the Incarnation) — Corruption as the natural consequence of creatures cut off from the source of life. Death as the trajectory of distance.
Maximus the Confessor — The logoi/tropos distinction: every created thing has a God-given rational principle (logos); evil is the distortion of the mode (tropos) in which that principle is lived out.

Contested Readings

Whether privatio boni adequately accounts for evil's active, predatory quality — Scripture presents evil as organized, aggressive, and personal (the serpent, the dragon, principalities and powers). The privation account explains evil's ontological status but can feel insufficient to its experiential weight. The essay inherits the patristic diagnosis while acknowledging this tension.

What the Framework Cannot Carry

The framework inherits the patristic account of evil's nature but does not resolve the full problem of evil: why God permits it, how long He will permit it, or what it means for those crushed under its weight before the homecoming arrives.
