The article is an attempt to present the difficulties encountered by people who want to apply rationality in science at any price. The text discusses an approach which competes with rationality and suggests the participation of an element belonging to the mythical - metaphysical order in forming scientific theories. The authoress wonders where the boundary between the true and false world (as understood by Nietzsche) runs. She tries to answer the question - is metaphysics actually ballast which makes the development of science impossible?
