This philosophical reflection examines the imprecise and often uncritical ways in which the concept of "fiction" is understood in contemporary thought. The author argues that we commonly categorize phenomena as fictional by using other, unrecognized fictions as benchmarks for reality. This tendency is particularly evident in ethics, where moral norms are often dismissed as subjective constructs, and in the reductionist view of biological life. Drawing on the example of ancient atomism, which posits that only "atoms and the void" are real while life is mere appearance, the text identifies this reductionist framework itself as a flawed and incorrect fiction. By deconstructing these erroneous perspectives, the author opens a path toward understanding life not as an illusion or a byproduct, but as a profoundly real and foundational aspect of existence. The abstract emphasizes that recognizing the ontological significance of life requires a critical re-evaluation of the scientific and philosophical constructs often mistaken for absolute reality. Ultimately, the document serves as a call to acknowledge life as a primary reality essential to our overall understanding of the world.
