When I saw this question, I immediately thought of this chart I saw when I was in school. It divides the needs into material and spiritual. The author is trying to point out that yes, you need material things, but spiritual needs are just as important. They’re essential parts of our life, our emotional stability.
The most important point in this chart is “Arts/Culture”. Where would we be without art? How would humans stay sane if they didn’t have a sense of community and safety within cultural structure? They are a part of us that we couldn’t live without. What if you were sent into space in a rocket ship, and watched as earth exploded, and you knew that you were the only human left? Would you want to live?
I think what I’m trying to say is that you need these spiritual things to survive. What is the point of surviving physically if you lose your mind? YOU wouldn’t survive. Only your body, but not your self. It’s a two way deal. For me, these are the things that I can’t live without; My family and friends; books to feed my mind with new ideas and philosophy.
