"Je pense donc je suis"
— Rene Descartes
Simplified Meaning:
This saying means that the ability to think proves that you exist. Imagine you are dreaming, and in that dream, you're unsure if anything around you is real. But you realize you can think about your dream and question it. This thinking shows that, at least in some way, you really exist. For example, if you're playing a virtual reality game and everything around you is fake, your thoughts about the game and what's happening show that there's a real you playing it. This idea helps people understand that no matter how unsure they are about things they see or hear, their thoughts prove they're real. To apply this, when you feel confused or doubtful about life or the world around you, remember that your ability to think is proof of your true existence.
