The recent development of biosemiotics has revealed the achievement of knowledge and the development of science to be the results of the semiosis of all life forms, including those commonly regarded as cultural constructs. Education is thus a semiosic structure to which evolution itself has adapted, while learning is the semiotic phenomenon that determines the renewal of life itself. Historically, it was a semiotic paradigm that determined the emergence of institutions such as universities and that underpinned the development of liberal education. The present article considers the history of education in terms of sign emergence and evolution, regarding education as currently being conceived and practised as a stage in the general evolutionary action of signs. This approach differs from the prevailing modern approaches to education, which are mostly applied psychology and sociology.
