The ontological difference established by Martin Heidegger between being and entity, as well as the question about what generates the word as proposition and sentence, when analyzing a fragment of Anaximander, brings us to the germinative center of ontopoiesis. Between what is revealed to knowledge or language and what is withdrawn from it as being still hidden, would be an abyss. What was thought or said would be only a trace of what is still unthinkable or is underlying speech never complete as a word. Being withdraws when it manifests itself. This phenomenon requires a proper method of analysis, not objectifying (representative) or eidetic (essential). Heidegger admits, nevertheless, a light emerging from being in the presence of what is presented. It is uncritical and does not confuse presence with the presented and much less with the represented. Such light is the energeia and what appears to be retracting can be considered a specific phenomenon (Ereignis): it brings together the multiple traits of being emerged and dispersed in different ways. This reflection reminds us, on the one hand, of the contextual horizon of poetic form outlined by Eduard von Hartmann, and on the other, of the creative concept of language and its energeia. The perceptive phenomenon already unravels thought’s germinating background. We propose to unravel the ontopoietic background of the dwelling of being in knowledge and language. Other authors such as Ángel Amor Ruibal, Ortega y Gasset, Paul Claudel and Anna Teresa Tymieniecka, accompany us in this reflection.
