Descartes argues that when the hardened wax melted it lost all the qualities that our senses could detect. So to our senses, the hardened wax vanished and a new thing appeared, the melted puddle. But our minds know that the hardened wax and the melted wax are the same physical thing. So he concludes that our mind, not our senses, is the source of that knowledge that the hardened and melted wax are the same thing. Is Descartes’ argument right? Do you think there is any way that he might actually have relied on our senses to know that the hard wax and the melted wax are the same thing? Explain.
