"[L]iberalism is above all an attitude toward life and society based on tolerance and respect, a love for culture, a desire to coexist with others and a firm defense of freedom as a supreme value. A freedom that is, at the same time, the driving force of material progress, of science, arts, and letters, and of a civilization that has produced sovereign individuals, with their independence, their rights, and their responsibilities that are always held in balance with those of other individuals, protected by a legal system that guarantees coexistence within diversity. Economic freedom is a key element of liberal doctrine but certainly not the only one."
