Researching the phenomenon of space contributes to knowing the Romanian mentality. Using the psycholinguistic method of the associative experiment, we submit to investigation the way Romanian people conceive space. The result of the research has shown that within the Romanian mentality space is an aspect of the world's existence, but not a frame or its primordial condition. Thus, space is not a phenomenon of its own or something detached, but an essential dimension of the world, an intrinsic fact of the nature of things. For that reason it is conceived as something real and alive. Romanian people see space through various ways of their spiritual aspirations. In the dominant mentality of Romanian people, space participates and is a prerequisite for what is going on inside it, representing one of the fundamental aspects of existence.
