Final answer:
Plato's metaphysical components are the world of forms, which is eternal and unchanging, and the physical world, which is in constant change and is an imperfect reflection of the world of forms.
Step-by-step explanation:
According to Plato, the two metaphysical components are the world of forms (or ideas) and the physical world. The world of forms represents the ultimate reality and is unchanging, perfect, and eternal. This world includes Forms such as the Form of goodness and beauty. In contrast, the physical world that we perceive with our senses is in a state of constant change and is considered an imperfect reflection of the world of forms. Plato's theory posits that particular objects in our world participate in or share in the form that gives them their identity. Hence, our understanding of a chair, for instance, is derived from our intellectual apprehension of the Form of 'chairness', which resides in the eternal realm of forms, rather than from the imperfect, physical examples of chairs that we encounter.
