(draft) In this chapter, I examine the most significant ethical questions surrounding memory, both at the collective and individual levels, as discussed in the literature. I begin by exploring the values associated with memory, including truth, accuracy, integrity, and broader social and political dimensions. I then address the concept of a duty to remember, particularly in the context of genocide and other human atrocities, and the complex questions this concept raises. Following this, I analyze the ethical challenges posed by forgetting, (...) focusing on its collective implications for forgiveness and its individual dimensions, such as the responsibility for forgetting and the right to be forgotten. After briefly discussing memory virtues—a topic that remains underexplored in the literature—I explore the ethical considerations surrounding the wishes of individuals with severe memory loss, such as those with dementia. Finally, I summarize ethical debates related to current and hypothetical cases of memory modification, erasure, and enhancement, highlighting their potential impacts on personal identity, agency, authenticity, moral responsibility, testimony, and their overall desirability.
