Apollonian and Dionysian. The dilemmatic constitution of human formation. The article deals with the dilemmatic constitution of the human formation between Apollonian and Dionysian. In the first place, the relationship and identity of three fundamental concepts of pedagogy is restored, that is, Bildung (formation), Erziehung (education) and Kultur (culture). After a significance of the Greek myth and its Nietzschean reading, the Apollonian and Dionysian instances are considered within a pedagogical-clinical reflection. The axial figure is the concept of transfiguration, around which revolve the dialectical categories of harmony and delirium, conformism and transgression, perception (of beauty) and liberation (of instinct), criticism and social clinic. The unity between the two cases, which perhaps resolves the dilemmatic constitution of the formation, is based on the principle of formation and on the concept of Fortbildung, which consists of taking Bildung beyond himself. Apolineo y dionisiaco. La constitucion dilematica de la formacion humana El articulo trata sobre la constitucion dilematica de la formacion humana entre apolineo y dionisiaco. En primer lugar, se restituye la relacion e identidad de tres conceptos fundamentales de la pedagogia, esto es, Bildung (formacion), Erziehung (educacion) y Kultur (cultura). Tras una significacion del mito griego y de su lectura nietzscheana, las instancias apolinea y dionisiaca se consideran dentro de una reflexion pedagogica-clinica. La figura axial es el concepto de transfiguracion, alrededor del cual giran las categorias dialecticas de armonia y delirio, conformismo y transgresion, percepcion (de la belleza) y liberacion (del instinto), critica y clinica social. La unidad entre los dos casos, que tal vez resuelva la constitucion dilematica de la formacion, se basa en el principio de formacion y en el concepto de Fortbildung, que consiste en llevar a Bildung mas alla de si mismo.
