Plato's Theory on Forms

Imagine a gooey decadent pastry warm and fresh from a bakery’s oven, meticulously cut, and gently placed on a small saucer, topped with a dollop of vanilla ice cream. Consequent to the description, what pastry does one have in mind? Corresponding with Plato’s Theory of Forms, it is essential to rank and assign standards or models to objects, for without them objects can be interchangeable and mistaken for another.

The pastry could be refrigerated, packaged or shipped; however, there is a standard defined that describes what encompasses a brownie.
Another example of a form is a mirror. What is constant in classification of the form of mirror is that it is to display a reflection of whatever is viewing the mirror. A mirror can take on any shape, but the form remains the same. Any reflecting object is a mirror. Take for example, cool ocean waters on a starry night.

Shape is malleable in a sense that it can be bent to meet a certain criterion, the standard being the form. Subsequently, a defined Form or standard must first be derived to allow for a shape to be configured.  
Because there is a difference in substantiality because of the definition of standards, there also is a difference between the physical world of matter and the world of Forms. The physical world of matter, like...
