In the article the author is analyzing questions concerning philosophy, theology and natural sciences in the philosophy of nature of Vjekoslav Bajsić. The synthesis which luckily evolved in (he Middle Ages concerning the Arisiotelistic image of nature related to the testimonies from the Bible, might have been the cause of forming the established feeling that it was the only definitely valuable. Nevertheless, the determining happened in the 17th century through the Galilean concept of nature as a »realistic« geometry or as the ultimate movement of bodies in space which could have been completely mathematically understood. In the case of a conflict between a theologian and a scientist of natural sciences, the theologian is the one to adapt for the scientist cannot change his necessary revelations which are being expressed through mathematical language. Theology and natural sciences have completely different methods and therefore they go separate ways, but successes of the new physics seem to confirm its presumptions. In the meantime the physical image of the world had changed and left the mechanism and determinism behind. Bajsić thinks that theology and natural sciences have different method, communication and goals and that this fact must be taken in consideration. Then the dialogue and the completeness between theology and natural sciences might probably be possible.
