The following article has a reflective character for design. Its purpose is to suggest hermeneutics as an exercise to understand and interpret its episteme through its historic journey. Differentiated here is a specific link between linguistic flow and on experience of the world we are given by design, which leads to worrying about their ontological essence. We propose thinking of a design with social, responsible and ethical sense, depending on its raison d’etre, which realizes its essence, the onto-designer. It is taken into account for this hermeneutical dialogue political, social, cultural and aesthetic domains as axes to interpret the meaning that ethics has in the discipline of design. The ontological reflection, here expressed for design, becomes important only from the hermeneutical language, showing the representations that are articulated in design practice. The suggested dialogic way places reading and reflection on the conceptual elements in design episteme.
