Human being as zoon politikon and philosophy as education of man - based on my detailed analysis of the first one of the three Heidegger's lectures on The Nature of Language (Das Wesen der Sprache 1957/58) in which he deals with the possibility of undergoing the experience of speech with the support of the onto-logical starting point, which is overcome by meaning-compliant thinking (besinnlicher Nachdenken) into a poetic experience with a word and with its relation to the entity and non-entity of a thing from the poem by Stefan Georg titled The Word (Das Wort) - to contemplate on the assumptions and limits of the apprehension of the philosophically-educative questioning as the nurture towards thinking, which should inevitably be preceded by the knowledge about what it means to be or not to be brought up in thinking.
