Nowadays, scholars and philosophers, who are enthusiastic for science, try their best to make scientism as a basis for contemporary man’s culture. These efforts are often accompanied by persistent efforts made by the pioneers of contemporary atheism to exploit this tendency, which is strongly supported by atheists, in order to confirm their worldview. The main purpose of this study is not to trace the consequences that may inflict man’s existence and fate because of such a worldview, but it will focus on criticizing the logical and epistemological foundations, upon which such attempts and efforts are based, in order to show the defect of scientism as a basis for the attempts of obliterating religion, deluding man, and abolishing the independence of human sciences.
