In modern times, an abstraction of the concept of "Space" from architecture and re-imposing it again to architecture through theoretical discussions is a process by means of which many fundamental aspects of "architectural space" have been tampered with. In this book, by having a brief reference to the fundamental aspects of the concept, the attempt has been made to explain the basic role of space in the self-realization of man. Furthermore, the dependency of this concept to that individual- social cultural identity of human being and his environment will be explained.
