Human beings breed these opposing faculties which help them in determining on the real ‘memory of the will’ and this process of ‘forgetting’ and memory suggests how responsibility originated. According to the author, the concept of ‘conscience’ has a long history and variety of forms behind it and he traces the development of this concept in the next part of the book. He maintains that one of the oldest and enduring psychologies on earth concerning memory is that if something needs to stay long in memory, it should be ‘burned in’ and only things that can never cease to hurt stays in the memory. As the author illustrates, man has always regarded blood, torture, and sacrifice as a means to create a memory for him and the most dreadful sacrifices and pledges, the most repulsive mutilations, and the cruelest rites of the religious cults etc substantiate this view. Nietzsche also analyzes how the ‘bad conscience’ or the other ‘somber thing’ came into the world which directs the book toward the genealogy of morals.
