Plato Roundness Of Basketball

According to Plato a property that is abstract or quality is considered a form; if you were to take a property of a certain object and separate the property from the object, that itself would contemplate a form. A basketball could be taken for example here where you can take the roundness of the object being the basketball in this case and separate the roundness from all of the other properties the basketball has like the weight and the color, focusing only of the roundness would be the form of roundness. Again here according to Plato roundness being the property in thought is a property that exist without even thinking about the basketball; the form in this case is an idea of which will exist individually of the ball itself and individually of whether somebody else is thinking of it. In this case it is important to understand that the form of roundness exist in all round objects not only balls; this form participates in the form of all other round objects.
The first property of form is that it is transcendent; in a way that a form cannot be physically perceived; it has no existence in space and or time where as a ball for example (material object) on the contrary can be physically perceived and does have a physical existence in space and in time. A form though does exist in a different way but not in an place or time and this is an important note because it explains why they are unchanging. The form of roundness for example is always the same in all places and in all times where it can be exemplified. A from can be exemplified in more than one place at the same time and not be exemplified in a physical manner for its existence. Be it the case that all objects that have the property of roundness disappears the property of roundness itself will not disappear and will always
