Blasphemy is considered as one of the perennial challenges that human societies are dealing with. Concerning about this challenge is not only confined to pious people, but a great group of politicians, open-minded theoreticians, artists and other social classes, as well. The problems corresponded to blasphemy can be classified into two main categories: concepts, domain and instances as well as discussion on the motives, reasons and justifications. In this thesis different attitudes toward both these categories are thoroughly reviewed and investigated.
