An idealist might tell Descartes' wax analogy by emphasizing the idea that the wax is not a physical object, but rather a mental construct. They might argue that the wax is a representation of our perceptions and ideas, and that it is only through our minds that we can truly understand the wax. They might also argue that the wax is a metaphor for the way our minds can shape and interpret our experiences, and that it is only through our minds that we can truly understand the world around us.
