Context: Traditional research on the fiction/non-fiction distinction is the fruit of an essentialist methodology in which the procedures of ontologizing and textualizing are assumed as obligatory. Ontologizing and textualizing form the basic discursive technique, in which analyses are focused on the object as the semantic centre. Theory of literary fiction – deeply rooted in Alexius Meinong’s theory of non-existent objects – is object-orientated and, as a result, is always ontologically involved/engaged. Problem: The re-description of the fundamental literary problems as a kind of epistemological experiment for which non-dualizing philosophy is a foundation. Considerations are aimed at providing answers/solutions to the three following issues: 1. Is it possible to connect non-dualism with a literary discourse about literary fiction? 2. What difference does the non-dualizing perspective make in comparison to a philologically-orientated discourse? 3. What difference does the non-dualizing perspective make in comparison to the constructivist approach to the problem of fiction? Approach: Mitterer’s non-dualism is considered from both the context of ontologically-orientated discourse about fiction and literary research and the context of constructivist discourse about fiction. Results: Mitterer’s non-dualizing conception may be considered a foundation of a radical non-essentialist way of thinking about literary fiction. As a result, the philologically-orientated research on literary text, focused on the explanation of its semantics, would rather move towards a culturally-, pragmatically-, and/or sociologically- orientated type of discourse. The notion of (literary) fiction should be reformulated as follows: fiction is not the reason for interpretation; fiction is the result of interpretation because the description comes from the object of speech (from-object-cognition). Implications: This is only an introduction to the project of a potential non-ontologizing discourse about literary fiction. Therefore it should be developed and discussed as the option for the dualizing type of the discourse as it still stirs up a lot of controversies.
