Do you think the world needs a concept?

I'll explain what I mean:<br><br>It's a simple analogy: **animals have simple need systems to keep them alive**, e.g. a need for food, a need for sex, a need for safety, a need for kinship, a need for fun.<br><br>But what about humans? I believe that **we humans have more complex need systems**, e.g. a need for meaning, a need for purpose, a need for philosophy, a need for perspective, a need for a vision of the future etc. We need to orient ourselves, to find a **concept that encompasses everything**, that helps us to **understand**, **explain** and **predict** what we encounter around us.<br><br>This concept is the foundation for all other concepts we have of the world. For example:<br><br>* **A religious person has God as their overarching concept** that makes the world make sense. Their concept of God explains why we are here, what our purpose is and what we must do to live a good life.<br>* **A scientific person has science as their overarching concept**. Science tells them why we are here, how to live a good life and what the purpose of life is. They **understand** themselves and the world through science, they can **explain** the world and **predict** events through science.<br>* **A philosophical person has philosophy as their overarching concept**. Philosophy makes the world make sense to them, helps them understand how to live a good life and what the purpose of life is.<br>* **A Marxist has class struggle as their overarching concept**. Through class struggle, they understand the world, explain the world and can predict what will happen in the future.<br><br>What do you think: do humans need a concept that encompasses the world?
