"Loss of innocence" refers to the transition from a state of naivety and purity to one of awareness and experience, often marked by exposure to harsh realities. This concept is commonly explored in literature and psychology, where individuals confront difficult truths about life, society, or themselves, leading to a more complex understanding of the world. In many stories, such as To Kill a Mockingbird by Harper Lee, characters experience this loss as they face injustice and moral dilemmas. This shift can evoke feelings of sadness or disillusionment, as the once-simple view of life becomes complicated by new knowledge and experiences.
