The members of a society where there are only very limited constraints, the individuals can develop their capacities to the fullest extent. Such a society will be called a free society. The constraints on liberty can be in the forms of external control or dominance. As a result of social evils like casteism also there can be controls for freedom. Serious economic inequality in the society can also bring in such controls. Why does control become necessary? 

• We can’t live in this world without some kind of control. 
• There will be differences of opinion among people regarding ideas and concepts. 
• There can be a hundred and one reasons for having differences in the society. 
• These differences may lead into open confrontations. People may fight on the roads as they drive. There can be quarrels about parking space.
• There can be fights regarding house or land. There can be differences of opinion even about presenting a drama. Things like this can lead to conflicts, physical violence, and even murder. 
• Therefore to settle arguments and control violence, every society needs some kind of control mechanism
• An ideal society is the one in which people can retain their ideas and by making their own conditions live as they wish.
