"“Peace is not mere absence of war, it is a virtue”, wrote Spinoza:“Pax enim non belli privatio, sed virtus est”. And he added it is “a state of mind, a disposition for benevolence, confidence, justice”. Indeed, there can only be true peace if people are confident. At peace with their political system. Reassured that their basic rights are respected. The European Union is not only about peace among nations. It incarnates, as a political project, that particular state of mind that Spinoza was referring to. It embodies, as a community of values, this vision of freedom and justice. I remember vividly in 1974 being in the mass of people, descending the streets in my native Lisbon, in Portugal, celebrating the democratic revolution and freedom. This same feeling of joy was experienced by the same generation in Spain and Greece. It was felt later in Central and Eastern Europe and in the Baltic States when they regained their independence. Several generations of Europeans have shown again and again that their choice for Europe was also a choice for freedom."
