The concept of space has always been a fundamental theme and issue since the beginning of philosophy and abstract thinking in ancient Greece, and has been fundamentally change due to cultural-historical changes of spatiality throughout the history of knowledge. At the beginning of philosophy, there was a metaphysical question about the beginning or the first cause of all things, to which the concept of space, as a fundamental concept, is the answer. The main lines of philosophical discourse in ancient Greece, (...) which flowed in the philosophy of Plato and Aristotle, were conceived in the context of Euclid's geometry and Ptolemy's worldview. In the modern era, Descartes, Leibniz and Kant tried to conceptually influence space with Copernican rotation and Newtonian physics. Finally, spatial imagery is challenged by the application of physiological problems through non-Euclidean geometry, and especially through phenomenology. Hence, the opening of phenomenological concepts in philosophy and other disciplines that focus on the concept of space could be of interest to researchers in the foundations of phenomenology. Therefore, the aspect of effort in this article is the descriptive analytical development of the opinions of three expert phenomenologists on space. These three philosophers base their theories on a critique of the way of speaking on space. This approach taken by Descartes and Newton has been completed in recent times. In this article, we discuss the philosophical foundations of these philosophers. We discuss the space with each of these three philosophers in terms of a key concept in their philosophical system. Therefore, for Cassirer, we discuss the concept of symbolic spaces, for Heidegger, the concept of being-in-the-world, and for Schmitz, the concept of surfaceless space and felt-bodily space.

This paper seeks to analyse the concept of atmosphere in the philosophical system of Hermann Schmitz, the founder of New Phenomenology, as a fundamental concept for understanding his philosophical system; he uses this concept to transcend the duality of subject-object as well as to show the hidden realities and the foundations of lived experience of reality, by looking at how phenomenological analysis is revealed. Beside being used in sciences such as physics, meteorology, and psychology, the term also refers to the (...) atmosphere as a concrete phenomenon; it is also an evidence of his understanding the phenomenology and reformulating it. This paper aims to show the connection between the concept of the felt-body (Leib), as the theoretical core of his work, and space and emotion as other key concepts in his philosophical system, by using the structural analysis of the concept and the phenomen of atmosphere.The result of the analysis in this paper shows the special place of the concept of atmosphere in Schmitz's philosophical system and its prominent role in establishing his method of New Phenomenology.
