The foundations of the Constitution in the political philosophy of Aristotle

For the utopia and its bases, Aristotle defines the conditions that should it has such as the site or location, it should be near a sea, population should be neither large nor small, because the state of large population would suffer from more disturbance and the state with small population would be subjected to the other states with large population, it should enjoy self sufficient. To show the importance of state as a theory we can mention the following:-
1- The conditions of utopia are so importance as a theory in politics in the modern age, which affect the contemporary constitutional law.
2- Justice could not be obtained save by the individual satisfaction; the moderate medium is the golden medium, which Aristotle had talked about, to obtain happiness.
3- The state should have a principle to secure freedom, democracy and rights practicing as they are the bases of any constitution.
4- Aristotle, as well as Plato, had paid a great interest in education and teaching in the Utopia system.
5- The both philosophers insisted on progeny or descendents as the base of establishing advanced state with individuals of a healthy intellects and physiology.
6- They focused on the educational system for children; the education subjects should be general, music and physical education are the first of these subjects. The state should be the only responsible for education as it helps in maintain the constitution.
