In the 20th century, philosophical treatments of dialogue emerged from thinkers including Mikhail Bakhtin, Paulo Freire, Martin Buber, and David Bohm. Although diverging in many details, these thinkers have articulated a holistic concept of dialogue as a multi-dimensional, dynamic and context-dependent process of creating meaning. Educators such as Freire and Ramón Flecha have also developed a body of theory and technique for using egalitarian dialogue as a pedagogical tool.
The term dialogue stems from the Greek διάλογος (dialogos, conversation); its roots are διά (dia: through) and λόγος (logos: speech, reason). The first extant author who uses the term is Plato, in whose works it is closely associated with the art of dialectic. Latin took over the word as dialogus.
The band's history goes back to 1969 when Kim Breitburg (vocals, keyboards, guitar), Viktor Bezugly (bass, vocal), Viktor Litvinenko (guitar) and Anatoly Deynega (drums) formed in Nikolayev the pop band Kodry (Кодры) which soon became one of the most popular in the city. It disbanded, as most of its members got drafted. Breitburg's next project Baikonur in 1975 signed with the JezkazganPhilharmonics. A year later they returned home, now as Gaudeamus, with Breitburg and his new line-up starting to explore the possibilities of the quasi-classical musical format, with the 30-minute art rock suite Zemlya Lyudei, Land of Humans. The elements of musical theatre were now featured in the band's stage shows, as well as first experiments with visual arts. Next year the band moved to the Novosibirsk Philharmonics where it was renamed into Gulliver. In 1977 they returned to Nikolayev, the line-up now featuring guitarists Viktor Litvinenko and Mikhail Pirogov, Viktor Radiyevsky (bass, vocals), Sergey Vasilchenko (keyboards, vocals), Anna Salmina (violin, vocals), Sergey Babkov (drums), as well as the brass section.
