A contribution from the conference 'The Second Avant-garde' (part of the grant-funded project 'The Myths, Language, and Taboos of the Czech Post-Avant-garde from the Forties to the Sixties'), which was held on 23 October 2007. The article considers Karel Teige's (1900-1951) attitude to the Avant-garde, particularly his attitude to echoes of the Avant-garde, and also his perception of the Avant-garde in the 1940s. Using examples, the article discusses Teige's perception of art as a dialectic fact. It considers his attitude to Hegel and the ideas of the art historian Max Dvorak (1874-1921), particularly Dvorak's conception of art history as history of the mind and Dvorak's call for a unity of art scholarship and art.
