Narrative Summary of Limits of Natural Selection

Overview: 

This essay by Chauncey Wright discusses the limitations of Darwin’s theory of Natural Selection as applied to the human mind, particularly in explaining human morality and intellectual capabilities. Wright argues that while Natural Selection can account for many aspects of the biological world, it fails to fully explain the emergence of human consciousness, reason, and morality. He posits that these aspects might be explained by a broader “constitution of nature” that Natural Selection presupposes, or perhaps through other unknown forces.

Main Parts:

  • Part 1: Reception and Proof of Natural Selection: Wright begins by acknowledging the widespread acceptance of Natural Selection despite incomplete proofs, attributing it to Darwin’s skillful presentation and Wallace’s independent observations.
  • Part 2: Utility and Adaptation in the Organic World: Wright explores the principle of utility and adaptation as central to Natural Selection, showcasing how this principle provides explanations for diverse aspects of organic life, such as the brilliant colors of caterpillars, and ultimately proving the theory’s predictive power.
  • Part 3: Limits of Natural Selection in Explaining Human Nature: Wright contends that the human mind, particularly its moral and intellectual capabilities, surpasses the explanatory reach of Natural Selection. He highlights features like the human brain’s size, the absence of hair, and the capacity for abstract thought as examples that defy straightforward explanations by Natural Selection.
  • Part 4: The Role of the Will in Human Actions: Wright engages with the question of the Will and its relationship to physical forces. He argues against the idea that the Will is a physical force, suggesting instead that it is a regulatory force that operates independently of the laws of physics, suggesting that conscious volition might be a purely regulative cause, adding nothing to the physical forces at play.

View on Life:

  • Natural Selection: Natural Selection is a powerful principle that explains a great deal about the biological world, but it has limits, particularly when applied to the human mind.
  • Utility: The principle of utility plays a fundamental role in understanding the adaptations of living beings and how Natural Selection works.
  • Metaphysical Views: Wright’s views suggest a broader “constitution of nature” beyond the realm of Natural Selection, hinting at metaphysical principles that govern the development of life and consciousness.

Scenarios and Situations:

  • The Galapagos Islands: Wright references the unique flora and fauna of the Galapagos as evidence for the transmutation hypothesis, showcasing the role of geographical distribution in shaping life forms.
  • The Gaudy Colors of Caterpillars: This anecdote illustrates how the principle of utility can be used to understand seemingly inexplicable features of living beings.

Challenges:

  • The Absence of Hair in Humans: Wright challenges Natural Selection’s ability to explain this specific feature, arguing that it defies straightforward explanations based on utility or correlated variation.
  • The Human Brain’s Size: Wright questions whether the large size of the human brain, even in primitive humans, is solely a product of Natural Selection, suggesting that it might represent a capacity beyond immediate need.
  • Moral Sentiments: Wright challenges the notion that morality is solely based on utility, suggesting that moral sentiments might stem from more fundamental instincts and social needs.

Conflict:

  • Natural Selection vs. Metaphysical Explanations: The essay’s central conflict revolves around the limitations of Natural Selection in explaining human nature, particularly in light of its intellectual and moral capacities. Wright presents an alternative perspective that embraces a broader “constitution of nature” or other, potentially metaphysical, factors.
  • Free Will vs. Determinism: Wright grapples with the question of free will, suggesting that conscious volition might not be a source of physical energy, but rather a regulative force that operates independently of the physical laws of the universe.

Plot:

The essay unfolds as a discussion between Wright and the reader, as he examines the arguments for and against Darwin’s theory, highlighting its strengths and limitations. The narrative arc explores the evolution of scientific thought regarding the origin of species, with a focus on the challenges posed by human nature to Darwinian theory.

Point of View:

The essay is written from a first-person perspective, allowing Wright to express his own opinions and insights on the limitations of Natural Selection. He presents his arguments in a reasoned and thoughtful manner, inviting the reader to consider his alternative perspectives.

How It’s Written:
