    How to recognize if you're self-interested (and whether that's actually harmful) - Mark Hopwood

    Explore a classic philosophical debate and decide: is it human nature to be selfish? And if so, is it possible to overcome it? -- The question of whether or not humans are inherently selfish is one of philosophy’s oldest debates. The idea that we only act out of self-interest is an extreme stance that few philosophers would endorse. However, the idea that all humans have a deep selfish streak is something many philosophers would agree with. So, are we innately selfish? Mark Hopwood explores this classic conundrum.
