Karel Miler got to doing actions in open space through his own poetry work, which, at the beginning of the 1970s, had a gradually stronger orientation towards conceptual expression. The disengagement of his text from the content led to minimalistic formulations with the simplest antimonies possible. The form became more significant at the expense of the semantic side and the significance of the message was co-created by, for example, the arrangement of words on the page. Miler further developed this principle when he was engaged in placing texts in three dimensional spaces. The piece Either – Or, which interconnected the text and “action” aspects, originated in 1972 in perfect succession to Miler’s previous projects.
Miler’s pieces from the first half of the 1970s reflect the experiencing of one’s own corporeality in space and through photographs they draw attention to the uncertainty of our existence in the world. In addition to other influences, Miler started focusing on phenomenological questions thanks to Jan Patočka’s lectures that he attended during his studies of art history at the Faculty of Philosophy at the Charles University in Prague. Miler distinctly differed from other Czech “action” artists of the 1970s with his approach to photography. His projects in space were actually not meant primarily for the eyes of an audience – his work was not finalized until he produced a series of photographs. During the second half of the 1970s Miler practically abandoned this principle of situations and polarities documented by two, three, four or five photographs with a clearly defined sequence and his work was developing in the direction towards projects with more action. Within a nearly decade the focus of Miler’s work gradually shifted from the theme of human orientation in the world, using photographed situations, towards projects with greater action, in order to get, in the second half of the 1970s, all the way to performances determined for the live public, with which Miler’s work was concluded in 1979.
