In history an additional result is commonly produced by human actions beyond that which they aim at and obtain -- that which they immediately recognize and desire. They gratify their own interest; but something further is thereby accomplished, latent in the actions in question, though not present to their consciousness, and not included in their design.
Georg Wilhelm Friedrich HegelRulers, Statesmen, Nations, are wont to be emphatically commended to the teaching which experience offers in history. But what experience and history teach is this - that people and governments never have learned anything from history, or acted on principles deduced from it. Each period is involved in such peculiar circumstances, exhibits a condition of things so strictly idiosyncratic, that its conduct must be regulated by considerations connected with itself, and itself alone.
Georg Wilhelm Friedrich HegelAn idea is always a generalization, and generalization is a property of thinking. To generalize means to think.
