"Movements seeking to change the world often begin by rewriting history, thereby enabling people to reimagine the future.  Whether you want workers to go on a general strike, women to take possession of their bodies, or oppressed minorities to demand political rights  -- the first step is to retell their history.  The new history will explain that 'our present situation is neither natural or eternal.  Things were different once.  Only a string of chance events created the unjust world we know today.  If we act wisely, we can change that world, and create a much better one.'  This is why Marxists recount the history of capitalism; why feminists study the formation of patriarchal societies; and why African Americans commemorate the horrors of the slave trade.  They aim to to perpetuate the past, but rather to be liberated from it."
