In the present essay, the French philosopher Quentin Meiyasu develops the theme of the constancy of the laws of nature, considering the possible relationship between chaos and order in the context of literary fiction and transcendental logic. Clashing the positions of Hume, Kant, and Popper, Meiyasu wonders what we mean when we talk about "the fiction of extra-scientific worlds"?, or "extra-scientific fiction"?, and identifies three types of worlds: worlds where both creation and science are possible; worlds where consciousness is possible and science may not be possible; and worlds where neither consciousness nor science is possible. "We mean by extra-scientific worlds such worlds where experimental science is not possible de jure, not just unknown de facto. Extra-scientific fiction defines a special mode of the imaginary, in which worlds are thought, structured - or, rather, destructured - so that experimental science can neither unfold its theories in them, nor construct its objects. One question directs extra-scientific fiction: what should be, what should the world be like so that it is de jure inaccessible to scientific knowledge, cannot become the object of some kind of science of nature?"?
