We know from our reading that everything as it exists has Form. A dog exists and takes the Form of a dog. Although all dogs are different, they all have the essence of a dog. Forms are standards or models. Plato says they do not change. A tree cut down is dead. But the Form of a tree does not die. So he believes that Forms are more real than things in the world of our senses.
Take something about an object, like the roundness of a basketball. Separate roundness from the ball and you are thinking about the FORM of roundness. It exists without the ball and all round objects copy it.
Forms are also unchanging. Around basketball never changes.

Describe the "Form" of some ordinary objects around you, in accord with Plato's theory. How did Plato view the physical world of matter in comparison to the world of Forms? And can we understand our recognition of objects without some concept of Forms to explain how it is that we recognize them?
