Radovan Richta
Radovan Richta (6 June 1924 – 21 July 1983) was a Czech philosopher who coined the term technological evolution; a theory about how societies diminish physical labour by increasing mental labour.Richta's first work was ''Člověk a technika v revoluci našich dnů'' ("Man and Technology in the Revolution of Our Day"), published in 1963. This work did much to bring the concept of technology into the forefront of philosophical thought during the 1960s. Richta then went on to publish ''Civilizace na rozcestí'' ("Civilization at the Crossroads") in 1966. "Crossroads" was a compilation work published by 60 authors (including and led by Richta) that "attempt[ed] to analyze the social and human implications of the scientific and technological revolution". The concepts touched on in "Crossroads" are considered by some philosophical historians to be very ground-breaking for their time.
Richta developed the famous term of "Socialism with a human face" serving as a motto of the Prague Spring period. He became the director of the Institute for Philosophy and Sociology of the Czechoslovak Academy of Sciences in 1969–1982. Provided by Wikipedia
