Critically Compare Plato’s Form Of The Good With Aristotle’s Prime
Mover
Both Plato and Aristotle argued that a metaphysical entity provides the ultimate
explanation for our physical reality. In Plato’s case this is the Form of the Good
(FOTG), as the source of intelligibility and existence which is the form of the forms –
giving definition and identity to the things we experience – and the only true form.
For Aristotle, this is the Prime Mover, which is the origin of movement and efficient
causation as well as the necessary being which sustains our universe of
contingencies. Plato’s FOTG and Aristotle’ Prime Mover (PM) are concepts that
attempt to explain ultimate reality i.e. the fundamental, supreme truth or nature of
existence, beyond our everyday perceptions. The thesis of this essay is that
Aristotle's PM offers a more coherent, and applicable explanation of reality due to its
grounding in empirical observation, its avoidance of speculative dualism, and its
relevance to scientific and theological inquiry.
Philosophically, Plato’s FOTG and Aristotle's PM both represent ultimate, perfect
realities but differ fundamentally in their nature, function, and the philosophical
approach used to derive them The FOTG is not a "being" in the personal sense but a
supreme, abstract ideal, existing in a transcendent "World of Forms" separate from
the physical world. It is "beyond being in power and dignity”. The PM is a "being" or
substance, an eternal, actual, and immaterial entity which is the ultimate cause of
motion. It exists as a necessary part of the single reality. The FOTG is never clearly
defined by Plato and seems to depend on his rationalist approach and theory of
forms. This begs the questions of “how can humans access a transcendent Form?
and why should a metaphysical ‘Good’ guide behaviour? Aristotle's PM offers a more
consistent metaphysical framework by integrating motion and causation within the
observable world. The PM is the necessary, eternal, and unchanging first cause,
causing motion as the object of desire and thought (Metaphysics, 1072b). It avoids
the dualism of Plato's Forms by being part of a unified reality. Plato's FOTG
transcends the physical world, providing a higher, eternal standard for morality and
knowledge (Republic, 509b). This is dualistic: Therefore, the FOTG's detachment
from the material world renders it speculative and disconnected from practical
application. Aristotle's immanent approach links metaphysics to observable reality,
making it more credible and grounded approach.
An understanding of the FOTG is gained through a priori reasoning and intellectual
contemplation, which is an arduous process of philosophical ascent (as in the
Allegory of the Cave) that is independent of sense experience. In contrast, the PM is
derived from a posteriori observation of change and motion in the natural world (the
empirical evidence of cause and effect. Aristotle's PM is more dependable and
accessible than Plato's reliance on innate knowledge and recollection. Aristotle
emphasizes understanding through observation and experience, with knowledge of
causes forming the basis of science. To counter this, Plato’s FOTG is accessed
through reason and intellectual ascent, as illustrated in the Allegory of the Cave
(Republic, 514a). It offers a higher epistemological standard, focusing on eternal
