Aesthesis is a fancy word that means our ability to sense or perceive things that are beautiful or pleasing to our senses. You know how you feel happy when you see a cute puppy or when you smell your mom's baking? That's your aesthetic sense at work! We use our senses - like looking, smelling, touching, listening, and tasting - to appreciate things that are visually pleasing, musically enjoyable, or even delicious to eat. So, the next time you feel happy because of something you see or hear, you can thank your aesthesis for it!
