If we look into the two processes of modernisation and secularisation together no doubt they are closely linked as both are part of a set of modern ideas. Modernization refers in social sciences to the process of evolution from the traditional into modern society.
Secularization marks a process in which especially in industrialized societies the religious beliefs, practices institutions have lost their former social importance, the traditional beliefs are subjected to rational questioning, the monopoly of religious symbols is broken with the pluralization of the life spheres and people have established more control on their environment with the rise of individualism.
As a result of modernization, there occurs a partition from religious thoughts and practices and even from the metaphysical conceptions in all realms of human life.
