This essay focus on Jean-Jacques Rousseau and David Hume and how they in their writings describe the doctrine of the original sin, and what they replace it with. The theoretical framework this essay work form, is Peter. L Bergers theories concerning society and religion as a social construction, were religious systems purpose is to establish order and previewed a meaning for people. From a history point of view religious system and institutions have had a significant role in establish system that will provide people with explanations about the world. In the eighteenth century, during the period in Europe often named as the enlightenment a new sort of criticism took place against religion. My study shows that in the part of Rousseau’s work Émile that goes under the name The Savoy priest's confession the doctrine of the original sin, is replaced with a faith in the human nature. Doctrines such as the original sin is for Rousseau something that is formed by humans in society, and has nothing to do with God. In the second part of Hume’s work Dialogues concerning natural religion, the dialogue shifts and focus on more moral concepts of religion, and also the question of evil, sin etc. Hume’s work presents three solutions instead of one.
