The first and main context of the paper is centered on the concept of SPACEbeing the most important and basic term of the expression put forward asTHE SCIENCES OF SPATIAL ORGANIZATION. The main questions formulatedabout the concept can be listed as: does the term space have only one concep- tual meaning (content) if not how and in which interrelations they are evolved historically how they are related withtheoretical, methodological and epistemological totalities? Even though thesecientific inquirers must use the concepts within the theoretical totalitiesthat they belong to; it is very crucial to differentiate between differentepistemological totalities, in which the teories and the concepts are placedin. We can evaluate the appropriate use of concepts and their conceptualmeaning only if we can specify their relation with the teoretical - epistem-ological totalities they are formed and placed in. For clear and appropriateundersanding of different epistemological approaches they must be relatedwith historical - social contexts. In the paper the introduced way evaluation and approach helps to see andformulate clearly the problems, the contradictions and the crises continuingwithin the sciences of spatial organization which are bing considered as asubset of social seciences.In sciences of spatial organization the physical dimensions of space are usu-ally separated from the social-economicalcultural-historical etc. dimen-sions of space. In fact the physical and socio-economical, cultural-historical etc. dimensions of space are unseparable, so they must bu held andanalysed together. It is not adequate or sufficient to accept the multidimen-sionality of space only at the conceptual level. The choice at the conceptuallevel must be integrated and unified with the choices at the theoretical,methodolgical and epistemological levels.In Turkey the work on the content of the concept of space has been consideredby the scientists those having natural (physics) and mathematical secien-tific bases (Oner, 1951, 1971, 1976; Koc 1984). Besides these work,within the context of the sciences of spatial organizalon, I. Tekeli (1967,1979) has evalutions on the concept of space and the different contents ofthe concept.Both In A. Einstein's (1969) and Max Jammer's (1969) approaches thehistorical evolution of the concept of space is taken as a linear, one dimen-sional and a successive process. If we summarise and clear the point, ac-cording to Einstein and Jammer the concept of space takes different contentswithin different periods throughout the history. These era's or periods areseparated with clear limits from each other and from one period to the oth-er; sequentially one content differentiates into the other. But Infect it is oneof the main thesis of this paper that the content of the concept of space hadan unhinear multi-Dimensional and compex historical process of evolutionThe evolution process has not taken the form as differentiation of one con-ceptual content into another in each specific historical period or era, but thechanges and transformations took place among synchronic conceptentualformations with crosswords interrelations and within historical conditionsand social determinants. The evolution of differentiations and transforma-tions are wavelike-unlinear but multicurved linear. The level and strengthof extention and approvability, of diffrent conceptual contents have beendifferent at the same historical period or era.
