Tiffany Watt Smith : The history of human emotions

TED 2017
Tiffany Watt Smith : The history of human emotions (transcript)
Summary
I see. Our emotions have often changed in response to new cultural expectations and ideas. It's sometimes very dramatically. It means that we humans have different emotions if they see the same thing. And then the words we use to describe our emotions seem to affect how we feel.
When our emotions are changing, the words are also changing, but we don't entirely capture what our emotions are.
Sometimes, it looks like a simple reflex, but our emotions are shaped not just by our bodies, but by our thoughts, our concepts, and language. It's immensely complex and elastic system.

Why is one of the speaker’s favorite emotion a Japanese word “amae”?
I think that for Japanese people, it's not a good situation. I wanted to learn the feeling of dependency like English speakers.
My parents were very strict when I was a kid. Enduring was beautiful but people must not show their emotions. Japanese Samurai has to serve their lord patiently. It must lead to the current generation. Thus when we learn people's emotions, we have to know their histories also.
After all, we explore feelings through words, but we might only understand the word meaning. When we learn its histories, we can understand the words well though we don't understand people's emotions right.
