I wish people would read some Foucault and realize that sweeping generalizations about how great the Enlightenment was are utterly reductive and unhelpful... I wish they would stop thinking so simplistically about it. Heart is making some very good points.
And anyway, if the Enlightenment was so wonderful, why did Imperialism and colonialism reach some of their most horrific apexes during and after?!? What about Enlightenment failed which brought about the Romanticist period?
