Abstract

In this article, I try to present some effects of the acceptance of nonconceptual content of perception in the realism problem. After having enhancement as main the problem of discrimination observable - unobservable into the conflict of realism with the constructive empiricism, I criticize a particular aspect, that nonconceptual content of perception strengthens the realistic position. Arguing that, while the starting point of the realist position is the existence of entities of common sense, there is nothing that assures us that the world of our daily life consists of objective, specific, unambiguous entities, that is made up the deep structure of the world - as realists believes - and entities are not just "relevant" objects, which are meant only for our own biological species. These “subjective for species” entities we are obliged, as a particular species, to percept with particular perceptual organs in order to satisfy specific needs, and manage to survive ourselves in a particular environment.
