The Covid-19 pandemic has revealed the serious crisis of political authorities that liberal societies are currently experiencing. Indeed, a significant number of individuals living in these societies did not hesitate to defy the sanitary rules enacted by their government which has made it difficult for them to stop the virus from spreading. What can explain such a situation? This is what this book is discussing. Whether it is the growing popularity of conspiracy theories, the distrust towards governments or cultural and religious beliefs that take precedence over the respect of governments’ directives, all these factors that have led so many individuals to act in an irresponsible way during the pandemic find their roots in the liberal tradition as it originated in the 18th century and in its more recent development which has had the effect of decentralizing the individual from his collective responsibilities in favor of an almost unlimited enjoyment of his individual freedom. This health crisis has revealed the urgency for liberal societies to establish a better balance between collective interest and individual freedom through responsible citizenship capable of protecting its citizens against the adoption of draconian measures when they will be struck again by upcoming pandemics that appear to be unfortunately inevitable.
