The third man argument

Definition

The third man argument is a philosophical critique raised by Aristotle against Plato's Theory of Forms, suggesting that if a Form (like 'largeness') exists for every property, then there must also be a Form of the Form, leading to an infinite regress. This critique highlights the complexities and potential absurdities in the Theory of Forms, questioning how these abstract entities relate to the particulars in the world.

5 Must Know Facts For Your Next Test

1. The third man argument illustrates Aristotle's challenge to Plato's idea of Forms by asserting that if a Form exists for each property, then there must be another Form that encompasses both the Form and its instances.
2. This critique points out that positing a separate Form for every instance leads to an unending series of Forms, complicating the relationship between abstract ideals and concrete objects.
3. Aristotle argues that the existence of such Forms does not help explain how we understand particulars, undermining Plato's claim that Forms provide knowledge and understanding.
4. The third man argument emphasizes the need for a more practical explanation of how universals relate to particulars, suggesting Aristotle’s preference for a more empirical approach to philosophy.
5. This critique is significant because it marks a fundamental shift from Plato’s idealism towards Aristotle's more grounded realism, impacting subsequent philosophical thought.

Review Questions

• How does the third man argument challenge Plato's Theory of Forms?
  • The third man argument challenges Plato's Theory of Forms by pointing out that if every property has a corresponding Form, then there must be another Form to account for the relationship between the Form and its instances. This leads to an infinite regress where each new Form would require yet another Form. This critique raises questions about the practicality and coherence of Plato's abstraction, suggesting that it complicates our understanding of how particular objects relate to their ideal Forms.
• What implications does Aristotle’s third man argument have on the understanding of universals and particulars in philosophy?
  • Aristotle's third man argument implies that the separation of universals (Forms) from particulars leads to confusion about their relationship. Instead of providing clarity, this separation results in an infinite number of intermediary Forms, making it difficult to see how these ideals truly relate to real-world objects. This critique suggests that a more integrated view is needed, where universals are understood as qualities inherent within particulars rather than existing in a separate realm.
• Evaluate how Aristotle’s critique through the third man argument reflects his broader philosophical approach compared to Plato’s views.
  • Aristotle's critique through the third man argument reflects his broader empirical approach which favors observation and tangible reality over Plato's abstract idealism. By questioning the necessity and practicality of multiple Forms, Aristotle emphasizes understanding through concrete particulars rather than relying on abstract entities that are disconnected from actual experience. This divergence lays foundational differences between their philosophies, with Aristotle advocating for realism and a focus on observable phenomena as opposed to Plato’s idealistic framework that prioritizes unchanging, abstract ideals.
