Beauty is not merely a matter of personal taste or fleeting fashion. The word encompasses such varied uses, from the judgment of a work of art to the appreciation of a moral gesture, that philosophy has sought to define a stable meaning since Antiquity. Aesthetics, the branch of philosophy dedicated to this question, today intersects with contributions from psychology, sociology, and neuroscience, without a consensus emerging on what makes something beautiful.
What digital filters reveal about the perception of beauty
A detour through contemporary technology exposes the fragility of our aesthetic judgments even before returning to classical definitions. In 2024, a study published in Royal Society Open Science found that images retouched by a beauty filter received distinct evaluations from those of the original photos. The gap was not only about perceived attractiveness: filters also altered the personality traits attributed to the face.
This finding indicates that the perception of beauty goes beyond mere visual pleasure and triggers social inferences. Beauty functions as a signal whose effects extend beyond the aesthetic realm to influence how we evaluate others.
The European regulation on artificial intelligence provides for transparency obligations for certain synthetic images. This regulatory framework acknowledges that manipulating beauty produces concrete effects on decisions and social judgments. Engaging in a reflection on beauty with Belle et Épanouie allows for an extension of this analysis into the realm of personal meaning.
Subjective or objective beauty: what philosophy resolves and what it leaves open
Does beauty reside in the object or in the gaze? This question has traversed the history of philosophy without ever receiving a definitive answer. It is this very tension that keeps the debate productive.
The Greek legacy: proportion, harmony, number
In ancient Greece, beauty obeyed measurable criteria. Classical sculpture follows canons of proportion, and the architecture of the Parthenon is based on precise geometric ratios. For the Pythagoreans, the beautiful coincides with the mathematical order of the world.
According to this approach, properties like symmetry or formal unity are sufficient to produce aesthetic pleasure, regardless of the viewer. Beauty would then be a quality inscribed in the object, not a projection of the observer.
The Kantian turn: the judgment of taste
Kant overturns this perspective in the 18th century. The judgment of beauty is no longer the description of an objective property: it reflects an inner state. Aesthetic pleasure arises from the free play between imagination and understanding, without a determined concept. The beautiful pleases universally without concept, according to the formula from the Critique of Judgment.
However, the Kantian position does not slip into relativism. Kant separates beauty from the agreeable, which varies from individual to individual. The judgment of beauty claims a subjective universality: I hold as beautiful what any sensitive person should also find beautiful, without being able to provide proof of it.
What remains unresolved
Contemporary philosophy has not settled this dualism. Some experimental psychology studies indicate that aesthetic preferences, such as for facial symmetry or certain color relationships, are found across cultures. Other research tempers this observation by showing that cultural context weighs as much as the formal properties of the work.
Longitudinal data that would allow for the separation of what pertains to perceptual constants (of neurological origin) and what pertains to cultural learning is still lacking. The boundary between the biological and the social, in the experience of beauty, remains an open field of investigation.
Beauty and aesthetic experience: beyond visual pleasure
Restricting beauty to visual appearance impoverishes a concept that is much broader. Philosophical aesthetics has always encompassed music, poetry, dance, natural landscapes, and even certain moral acts referred to as “beautiful gestures.”
- The sonic beauty of a musical work engages the ear, bodily rhythm, and affective memory, without any visual component.
- A moral gesture deemed beautiful, such as an act of bravery or a sacrifice, mobilizes an ethical as well as aesthetic judgment, blurring the boundary between the two realms.
- The natural beauty of a landscape combines formal elements (light, composition) with an existential dimension related to the feeling of being in the world. Kant spoke of the sublime when nature exceeds our capacity for representation.
Aesthetic experience is therefore not a passive pleasure. It involves an activity of consciousness that organizes, interprets, and assigns meaning to what it perceives. Beauty is as much a mental construction as it is a property of the world.
Beauty standards and social surveillance: a contemporary phenomenon
Aesthetic norms do not solely descend from philosophical treatises or museums. They are constructed, contested, and regulated in daily interactions, particularly online.
On social platforms, comments on physical appearance function as a regulatory mechanism, imposing or challenging beauty standards. Aesthetic norms are publicly negotiated among peers, not just through media or scholarly discourse.
This phenomenon puts pressure on the classic distinction between natural beauty and artificial beauty. When a digital filter alters a face, when an online comment penalizes a deviation from a norm, the boundary between what is perceived as beautiful and what is prescribed as such becomes blurred.
No definition closes the debate, because the very object of beauty transforms with techniques, cultures, and eras. What persists is beauty’s ability to provoke a pause in the flow of experience, a moment when consciousness turns to what it perceives in an attempt to grasp its reason.
