" Alternatively, there are ‘political’ schools of history, slanted to discredit the actions of our past leaders, in order to support modern political movements. In all these cases, history is not an attempt to ascertain the truth, but a system of propaganda, devoted to the furtherance of modern projects, or the gratification of national vanity.

Men can scarcely be blamed for not learning from the history they are taught. There is nothing to learn from it, because it is not true. "
