Since 2012, Aeon has been publishing some of the most profound and provocative thinking on the web. It asks the biggest questions and finds the freshest, most original answers, provided by world-leading authorities on science, philosophy and society. Aeon has four channels, and all four are completely free to enjoy. Most weekdays, it publishes Essays – longform explorations of deep issues written by serious and creative thinkers. Under the Philosophy channel, there is a metaphysics subject.
