Ahistoricism refers to a lack of concern for history, historical development, or tradition. Charges of ahistoricism are frequently critical, implying that the subject is historically inaccurate or ignorant (for example, an ahistorical attitude). It can also describe a person's failure to frame an argument or issue in a historical context or to disregard historical fact or implication. The term can also describe a view that history has no relevance or importance in the decision making of modern life. Look up ahistorical in Wiktionary, the free dictionary.
