It's sometimes counterintuitive to think that emotions might have a history, because surely everyone across the world and everyone across time has always felt fear and anger and sorrow and joy in the same kind of way.

Key Points• Emotions aren't fixed; how we express and understand them changes across time and cultures.• Some emotions, like boredom or nostalgia, were named and defined in specific historical moments.• Societies have unspoken rules about which emotions are acceptable and when.• Some of the emotions that are going to become more spoken about are emotions to do with our response to the climate crisis.
