What does freedom mean to you? Is freedom the ability to go where you want? To dress and act the way you want without anyone saying anything? Freedom is often subjective. Where one person may wage war for the freedom of his country, another person may suffer under the same authority without realising they are doing so. Freedom often comes with a price. But if there is a price to be paid, it is not really free. While Leiden still celebrates its victory over the Spaniards every year, no one understands freedom better than Kaunas: our fellow City of Science in Europe.
