Laughter is vital

For philosopher Henri Bergson, laughter is what keeps us elastic and free. "The philosopher recognised that laughter doesn't always bring out the best in us – it can be used to mock and degrade others. But at its core, its function is to remind us that to be human is to be alive and free." From the perspective of the French philosopher on the subject, Emily Herring contemplates why laughing is an essential window to life itself.
