The paper deals with mutual interdependence between philosophy and natural sciences. This correlation of two fundamental modes of human rationality can serve for breaking the limits of idealistic epistemology and classical phenomenology.Philosophical doctrines that aim to analyse the existence (human and/or general) and do not take scientific research seriously can‘t be taken as valid or acceptable. On the other hand, different reductionistic and mechanistic scientific worldviews are already inconvincible.Deeper understanding of scientific attitude towards nature opens up new paths for philosophy, especially hermeneutical tradition to quit with different forms of solipsism (existential as well as epistemological) and approach man as an integral part of cosmic harmony which  in turn contemplates and gives meaning to this order. Hence, the fundamentals of the universe are beyond human sense – giving constructions (culture, science) yet comes to everyday world only through these.
