From the Scientific Literature

Srbislava Sahovic Misic

“Naturalists are not usually prone to meditation. … Once in a while among them someone appears who helps the interest and ability to look into the base of transient phenomena which remain the object of study in natural sciences. … Hence the need in their work to set up a transition of a kind between the essence and phenomena. In that way they are similar to philosophers.” (Ksenija Atanasijević, Reflections of a Philosopher, Ivan Djaja “Downstream”)
