Many people ask why do we study classics and what do they have to teach us in our era. Beyond historical curiosity of how people lived in the distant dead past, knowledge of the classical period must have some utility in improving our life and help solve our problems to make its study worthwhile. This short exposition attempts to answer this question by a grand synthesis of the comparative study of classical theory and modern reality. Our fundamental thesis is that the Greek conceptualization of the ancient polis and its regional environment corresponds quite well with the contemporary notions of the post-modern city in the global system. 

In order to show this correspondence in a systematic way, we adopt an abstract approach utilizing a space-existence-time (SET) taxonomy and input-transform-output (ITO) methodology. As introduced and expanded in the author’s book Exopolitics, this approach combines the substance of our polis-ethnos-cosmos (PEC) theory with the process of its dialectical method.
