The text reconstructs the implicit ontology of an author’s work in the copyright law of the Czech Republic (law no. 121/2000 “Sb”), and in its commentary, published in 2007 by Ivo Telec and Pavel Tůma. To this purpose, the findings of the philosophy of artefacts and of the ontology of artists’ work are made use of. The concluding section of the article is devoted to providing a critical evaluation of the identity conditions of an author’s work in the Czech legal framework, which does not take into proper account the so-called causal dimension of an author’s works.
