Only passions, and great passions, can raise the soul to great things. Without them there is no sublimity, either in morals or in creativity. Art returns to infancy, and virtue becomes small-minded.
Denis DiderotAll things must be examined, debated, investigated without exception and without regard for anyone's feelings... We must run roughshod over all these ancient puerilities, overturn the barriers that reason never erected, give back to the arts and sciences the liberty that is so precious to them.
Denis DiderotWhich is the greater merit, to enlighten the human race, which remains forever, or to save one's fatherland, which is perishable?
