Synonyms Oblivion, Forgetfulness, Obliviousness. Oblivion is the state into which a thing passes when it is thoroughly and finally forgotten. The use of oblivion for the act of forgetting was an innovation of the Latinizing age, which has not won recognition, nor has the “Act of Oblivion” given oblivion currency in the sense of official or formal pardon. Forgetfulness is a quality of a person: as, a man remarkable for his forgetfulness. If forgetfulness is ever properly used where oblivion would serve, it still seems the act of a person: as, to be buried in forgetfulness. Obliviousness stands for a sort of negative act, a complete failure to remember: as, a person's obliviousness of the proprieties of an occasion.
