Love is a happy coupling relationship between two or more individuals - taking the Eudaimonia of the other as a component of one’s own Eudaimonia (the first principle), with non-infringement as the bottom line and actively defending the core Eudaimonia of the other party (the second principle), and jointly designing, maintaining and iterating each other’s Eudaimonia environment as the practical path (the third principle).
This is the definition of love given by “Ethics of Eudaimonia”
Within the framework of the Ethics of Eudaimonia, love is not a mysterious emotion or a priori obligation, but rather a pattern of interpersonal interaction that can be structured and understood through a three-layer principle.
The dimension of the first principle: Love as empathy and promotion of Eudaimonia
The starting point of love lies in incorporating the other person’s Eudaimonia into one’s own Eudaimonia function. When one person loves another, the satisfaction of the other’s needs (survival, expression, curiosity, pride) directly becomes the source of one’s own Eudaimonia - the other’s joy is one’s own joy, and the other’s pain is one’s own pain. This deep coupling of Eudaimonia makes “promoting the other’s Eudaimonia” a self-driven behavior.
The second principle’s dimension: Love as the bottom-line guarantee of non-infringement
Love is not unconditional sacrifice, but rather the absolute defense of the other’s core Eudaimonia. In a loving relationship, the second principle (not infringing upon others’ Eudaimonia) is strengthened into an active defense mechanism: love means never actively harming the other and being the most resolute protector when the other is under external threat. This sets a clear ethical boundary for love - any manipulation, belittlement or deprivation carried out in the name of love has already betrayed the essence of love.
The third principle’s dimension: Love as the co-construction of a common environment of Eudaimonia
The highest form of love is not possession but the joint creation of an environment where both can thrive. This means: (1) respecting each other’s right to pursue Eudaimonia independently and not imposing one’s own model of Eudaimonia on the other; (2) seeking consensus through negotiation rather than coercion during conflicts; (3) jointly addressing external challenges to make the environment for each other’s Eudaimonia more resilient. Love thus becomes the “co-creation of a happy environment” at the smallest unit - a cooperative system jointly designed, maintained, and iterated by two (or more) people.
Pathological Diagnosis of Love
Eudaimonia Ethics also provides tools for identifying “false love”:
When one party deprives the other of their right to make autonomous choices in the name of “having their best interests at heart”, this violates the first principle (respecting the other party’s right to define their own Eudaimonia) and the second principle (not infringing upon others).
When love is entirely based on negative pride (zero-sum comparison, possession and control), it has degenerated into a power relationship rather than true love.
When there is no shared space for the third principle in a loving relationship (where one party sets all the rules and the other can only obey), this is closer to a master-slave relationship than a loving one.
Summary of Definitions
Based on the three-tier principle, the definition of love in the Ethics of Eudaimonia is:
Love is a happy coupling relationship between two or more individuals - taking the Eudaimonia of the other as a component of one’s own Eudaimonia (the first principle), with non-infringement as the bottom line and actively defending the core Eudaimonia of the other party (the second principle), and jointly designing, maintaining and iterating each other’s Eudaimonia environment as the practical path (the third principle).
This definition liberates love from the enigmatic fog of romanticism, transforming it into an understandable, assessable, and optimizable ethical relationship framework. It acknowledges the emotional essence of love while endowing it with a clear normative structure - love thus ceases to be an “indescribable” entity and becomes a project of Eudaimonia that can guide practice, diagnose pathology, and promote growth.
