Japaridze's polymodal logic is like playing pretend with different hats on. Pretend that you're a chef, and you have a chef hat on. You know how to make food and what ingredients you need. But then, pretend that you're also a doctor, and you put on a different hat. As a doctor, you know about medicine and how to help people feel better.
Now, imagine that there are lots of different hats you can wear, like a scientist hat or a musician hat. Each hat represents a different way of thinking or knowledge that you have. Japaridze's polymodal logic allows you to switch between these different hats and think about things from different perspectives.
So, for example, if you're thinking about a problem, you might put on your scientist hat first to think about it logically and experimentally. But then, you might put on your artist hat to think about it creatively and visually. By using polymodal logic, you can combine all these different ways of thinking and knowledge to solve a problem or understand something more deeply.
