Pleonexia is the disordered desire to have more than one’s rightful share that is due, specifically when that gain comes at the harm and expense of another or violates the proper order of sound justice.
Pleonexia (πλεονεξία), from pleon (more) and echein (to have), translates literally as the desire to have one’s share and more. But the treacherous Bible translators tame it. Aristotle gives the word its teeth back. For Aristotle, pleonexia is not merely greed. It is an assault on justice. The pleonextic man puts his own gain above God’s righteous order.
In the Nicomachean Ethics, Aristotle identifies pleonexia as the motive behind all injustice properly so called. The unjust man is not simply the man who takes too much; he has oriented his soul around taking it all and has made acquisition the telos of his life rather than eudaimonia: flourishing in accordance with virtue and reason.
Wealth is not the sin. There is nothing wrong with having wealth. It is the orientation toward gaining it at the cost of destroying others. Aristotle’s ethics are teleological. Every vice is a disorder of the soul’s end. Pleonexia is the disorder that mistakes having for being, that confuses the accumulation of power, wealth, or honor with becoming something that only belongs to God. The pleonextic man is not just wrong in his actions; he is wrong in his own definition of self.
Aristotle extends the concept into political philosophy in the Politics. Tyranny, oligarchy, and democracy in its corrupt form are, at root, pleonextic regimes, governments oriented toward the advantage of the rulers rather than the good of the individual. The tyrant wants more power. The oligarch wants more wealth. The demagogue wants more popularity. Each has mistaken political office, which exists to oversee the polis, for an instrument of individual gain.
Aquinas inherits Aristotle’s pleonexia but sharpens it theologically. For Aquinas, pleonexia goes beyond a disorder of the rational soul. It places the creature in God’s place. To grasp more than your due is to reject the order of charity, the rightly ordered love of things according to their true value. Glory, wealth, and power belong finally to God. They are His. The creature who grasps for them has not merely disordered his nature; he has reached for what his nature cannot sustain.
The pleonextic man inverts this. He places his own having at the center of the moral universe and subordinates persons, justice, and God to that unrighteous appetite. Aquinas connects it directly to avarice (avaritia) as a capital sin but distinguishes the two carefully. Avarice is the disordered love of money, specifically. Pleonexia is the broader principle, the grasping disposition that can attach itself to wealth, power, control, honor, or anything else the soul misdirects itself toward. A government can be pleonextic. An ideology can be pleonextic. A culture can be pleonextic.
Against pleonexia stands the Incarnate God. Philippians 2:6, 7 describes Christ as One “who, although He existed in the form of God, did not regard equality with God a thing to be grasped, but emptied Himself, taking the form of a bond-servant, and being made in the likeness of men.” The Greek is harpagmon: seized, clutched, exploited. The contrast is worth understanding. Pleonexia grasps. Jesus surrenders.
But the kenosis is not loss. Christ surrendered the prerogatives of glory, not His glory and certainly not His Godhood. He did not subtract from Himself. He moved through death into resurrection, through the cross into exaltation. John 17:1: “Father, the hour has come; glorify Your Son, that the Son may glorify You.” And again, in verse 5: “Now, Father, glorify Me together with Yourself, with the glory I had with You before the world was.”
The writer of Hebrews teaches: “who for the joy set before Him endured the cross, despising the shame” (Hebrews 12:2). Paul closes the kenosis hymn the same way: “For this reason also, God highly exalted Him, and bestowed on Him the name which is above every name” (Philippians 2:9). He was crucified and died, He was raised, He is seated with God. That is not sacrifice as subtraction. Christ surrendered nothing that diminished who He is. The Cross did not make Him less; it revealed Him in His finest Glory.
This is why pleonexia cannot account for Christ. The pleonextic man grasps because he lacks. He hoards because he fears loss. His entire orientation assumes scarcity at the soul’s center. Christ lacks nothing. Through Him all things were made, and in Him all things hold together. He is the I AM of Exodus 3:14. He is Aseity, the Self-Existent God. Nothing can be added to Him because nothing is absent from Him. Pleonexia cannot exist in the God Who possesses all things by nature.
And this is the pattern set before us. When we choose Christ, we do what He did. We give over the lesser thing for the greater. What is surrendered for Christ is never worth more than Christ Himself. The pleonextic man clutches what is not rightly his and calls the taking gain. The one who follows Christ opens his hands. The grasping man builds his identity out of what he can take. Christ’s identity precedes creation itself. That is the distance between pleonexia and the gospel.
