Art

Art is the product or process of deliberately arranging items (often with symbolic significance) in a way that influences and affects one or more of the senses, emotions, and intellect.

It encompasses a diverse range of human activities, creations, and modes of expression, including music, literature, film, photography, sculpture, and paintings.

Art is something that stimulates an individual's thoughts, emotions, beliefs, or ideas through the senses.

It is also an expression of an idea and it can take many different forms and serve many different purposes.

Art stimulates different parts of our brains to make us laugh or incite us to riot, with a whole gamut of emotions in between.

You could say "Art is something that makes us more thoughtful and well-rounded humans."
