This book, which presents a cognitive-semiotic theory of cultural evolution, including that taking place in historical time, analyses various cognitive-semiotic artefacts and abilities. It claims that what makes human beings is fundamentally the semiotic and cultural skills by means of which they endow their Lifeworld with meaning. The properties that have made human beings special among animals living in the terrestrial biosphere do not derive entirely from their biological-genetic evolution, but also stem from their interaction with the environment, in its culturally interpreted form, the Lifeworld. This, in turn, becomes possible thanks to the human ability to learn from other thinking beings, and to transfer experiences, knowledge, meaning, and perspectives to new generations.weiterlesen
