Final answer:
Form is the actual, three-dimensional shape of an object and can be geometric or organic. In philosophy, the concept of form is associated with the idea that every particular thing participates in an immaterial form or essence. For Plato, forms are unchanging and eternal, existing in a separate realm, while Aristotle sees form as the unchanging purpose or idea that informs each individual instance of a thing.
Step-by-step explanation:
Form refers to the actual, three-dimensional shape of an object. It can be geometric or organic, and it can also be used to describe the illusion of three-dimensionality. In philosophy, the concept of form is associated with the idea that every particular thing that exists participates in an immaterial form or essence that gives it its identity. Plato believed that these forms were unchanging and eternal, existing in a realm separate from our changing world. Aristotle, on the other hand, saw form as the unchanging purpose or idea that informs each individual instance of a thing. He viewed form as part of a composite of matter and form, where the material cause is the physical substance and the formal cause is the unchanging purpose or whatness.
