During the 18th century a new spirit was born (in essence a continuation of the Renaissance) which swept away the older values of the Baroque and received the name of "Enlightenment". This movement laid its foundations in a critical spirit, in the predominance of reason and experience, philosophy and science being the most valued sources of knowledge. The period is also known as the "century of lights" or the "century of reason". In short, human happiness was pursued by means of culture and progress. Art and literature were oriented towards a new classicism (Neoclassicism). Expressions of feeling were avoided, norms and academic rules were followed, and balance and harmony were valued. A century of so much rigidity led to a reaction in the form of a return to the world of the emotions; this movement is known as "Pre-romanticism".
