Star Trek: TNG is as much about emotional intelligence as it is about exploration.
Because you NEED emotional intelligence to understand why the Prime Directive is the only thing you need to remember.
The Prime Directive is the Golden Rule: Live and Let Live.
That's why I love it so much. Don't interfere with free will. They fucking deal with it. They fully accept one another. They sit with their pain.
And it's not about their fucking guilt or jealousy or other metaemotions.
The simplicity of it affects every aspect of their lives. When they judge, they make it right. They don't bitch about it and flounce off.
They ACKNOWLEDGE reality, doing their best to do so without expectation, need, or assumption, but while also fully acknowledging their own perspective.
That is how the fuck you do ethics!
