Definitions of the Enlightenment;

The role of science and technology in the shaping of modern European societies, specifically of English and  British society: the new jobs, the development of manufactures and some groundbreaking English industries, the expansion of (inter)national trade and the new economic theories to help its development.

The revolutionary changes (either by force or by legislative reforms) in social and political systems: the creation of modern democracies as well as imperial ideologies.

Kant's audacity to know and decide in one's own name.
