Modernity

"Modernity refers to the historical period and social condition that began roughly in the 17th century, marked by industrialization, urbanization, secularization, rationalization, and the rise of nation-states and democratic ideals.  It is characterized by a belief in progress, science, reason, individualism, and the Enlightenment project. Modernity is a broad, structural reality—something everyone lives within, whether they embrace it or not."
