Oh hello there little one! Let me tell you about something called "the imaginary" which was talked about by a philosopher named Sartre.
So, have you ever played pretend or imagined something that wasn't real? Well, Sartre talked about how sometimes we imagine things that aren't really there, but they can still have an effect on us.
For example, let's say you're scared of spiders. Even if there isn't a spider around, you might imagine one and that can make you feel scared and anxious. That imagined spider is what Sartre called "the imaginary".
Now, sometimes people might use the imaginary to try and escape reality. They might imagine things that make them feel better, like pretending to be a superhero or imagining they have lots of money. But Sartre warned that relying too much on the imaginary can be a problem.
He said that it's important to face reality and not get too caught up in our imaginations, because it can keep us from living in the real world and experiencing things as they really are.
So, that's a simplified explanation of what Sartre meant by "the imaginary". It's all about how our imaginations can affect us, but we need to be careful not to rely on it too much and forget about what's really happening in the world around us.
