Plato is considered one of the pioneers of Greek Philosophy Who appeared in the 4th . C.B.C. and who had participated greatly to the development of the Greek civilization . Those Philosophers opinions had affected greatly the ancient as well as the modern worlds. Since Plato's writings have had their impact the present research aims of uncovering an aspect of Plato's cognitive effect through studying his opinions on the Greek geographical thought . Plato's geographical concepts are scattered in his Philosophical books and this required gathering these concepts in one comprehensive study. Here lies the importance of this research in documenting and verifying those concepts by going back to their original sources. The structure of the research Shows that Plato had a great effect on the Greek geographical thought ; an effect that is apparent in many of his geographical ideas which appeared in the branches of human and natural geography and which represented at that time (a long with the other Philosophical sciences) the pillars on which the Greek civilization was built.
