Is Free Will an Illusion?

Imagine a line of dominoes. When the first one falls, it hits the second, then the third, and so on. This is how some people see the world: every event causes the next one. If you know exactly how big each domino is and where they are standing, you could predict which way they will fall forever.

In this view, your brain is like a giant machine of tiny dominoes. When you decide to eat an apple instead of a cookie, it is because your hunger (the cause) led to the choice (the effect). There was no other option possible at that exact moment.

However, you feel like you are choosing. You sit in your chair and wonder what to do next. It feels like you have a special power called free will to pick any path you want. Scientists call this the feeling of agency. Even if our choices are caused by earlier events, they still feel real to us.

So, is free will real? Or is it just a trick our minds play on themselves? It might be like a dream. In a dream, everything happens naturally, but you believe you are flying. Maybe when we wake up to the truth of physics, we see that free will was always there, hidden inside the dominoes.
