Medieval Aesthetics: Beauty as Transcendental

Augustine of Hippo (354-430 CE), whose early philosophical formation was decisively shaped by his reading of Neoplatonist texts, develops an extended theory of beauty grounded in number, proportion, and unity across several works, notably De Musica, begun around 387 CE, and De Vera Religione (390 CE). For Augustine, all created beauty consists fundamentally in numerus, a rhythmic or numerical proportion, and in aequalitas, equality or fittingness of parts, both of which ultimately reflect the perfect, unchanging order of the divine mind; a thing is beautiful in proportion to the degree that its form participates in this numerical harmony. Deformity or ugliness, correspondingly, is explained not as a positive contrary force but as a privation of due form and order, directly paralleling Augustine's more famous privative account of evil as a lack of good rather than an independent substance, developed in the same period against Manichaean dualism.
