The Platonic Forms, according to Plato, are just ideas of things that actually exist. They represent what each individual thing is supposed to be like in order for it to be that specific thing. For example, the Form of human shows qualities one must have in order to be human. It is a depiction of the idea of humanness.
Where do Forms exist Plato?
So what are these Forms, according to Plato? The Forms are abstract, perfect, unchanging concepts or ideals that transcend time and space; they exist in the Realm of Forms. Even though the Forms are abstract, that doesn't mean they are not real. In fact, the Forms are more 'real' than any individual physical objects.
What is the Platonic world?
