Understanding Aristotle's Function Argument

Aristotle's concept of ergon, or function, is a cornerstone of his ethical philosophy, particularly as detailed in the Nicomachean Ethics. He posits that the good for any entity – be it an object, an organism, or a human being – is intrinsically linked to its characteristic activity or purpose. By identifying the unique function of humans, Aristotle aims to define the highest human good, which he identifies as eudaimonia (often translated as flourishing or living well).

Structure of the Function Argument

The argument typically follows a pattern of analogy and elimination. Aristotle begins by observing that things have functions: a shoemaker makes shoes, a harpist plays the harp. The excellence of these things is determined by how well they perform their respective functions. He then applies this logic to human beings. He considers and rejects functions shared with other living things, such as nutrition and growth (shared with plants) or sensation and locomotion (shared with animals). He concludes that the distinctive capacity of humans is reason. Therefore, the human ergon is 'activity of the soul in accordance with reason.' The highest human good, eudaimonia, is achieved when this function is performed excellently, meaning 'in accordance with virtue.'

Thesis and Claim

The central thesis of the ergon argument is that the good for a human being is found in the excellent performance of their unique, rational function. This is not merely about possessing reason, but about actively engaging in rational activity throughout a complete life, guided by virtue. The claim is that this specific mode of activity constitutes the highest form of human flourishing and constitutes the objective standard for a good life.

Evidence and Reasoning

Aristotle's evidence is primarily based on observation of the natural world and the common understanding of excellence in various crafts and professions. His reasoning is analogical: just as a good knife cuts well, a good human lives well by performing their characteristic function well. The 'evidence' for reason being the unique human function comes from a process of elimination, comparing human capabilities to those of plants and animals. The definition of virtue as the mean between extremes, developed through habituation, serves as the mechanism for performing the rational function excellently.

Organization and Flow

The sample essay follows a logical progression. It opens with an introduction establishing the importance of the ergon argument in Aristotle's ethics. It then explains the core logic of the argument, using analogies and outlining the process of identifying the human function. The essay details how this function relates to eudaimonia and virtue. Subsequently, it addresses common criticisms and ambiguities, demonstrating critical engagement. Finally, it concludes by summarizing the argument's enduring relevance. This structure moves from exposition to analysis and evaluation, mirroring standard academic essay organization.

Tone and Style

The tone is formal, academic, and analytical. It aims for clarity and precision, using discipline-specific terminology (ergon, eudaimonia, telos) where appropriate, but explaining these terms for accessibility. The style avoids overly complex sentence structures while maintaining a sophisticated vocabulary suitable for philosophical discourse. It presents Aristotle's ideas fairly before introducing critical perspectives, maintaining an objective stance.

Revision Opportunities

  • Deepen the analysis of criticisms: While criticisms are mentioned, a deeper dive into specific philosophical objections (e.g., from natural law theorists, existentialists, or contemporary ethicists) could strengthen the evaluation section.
  • Expand on 'virtue': The essay could benefit from a more detailed explanation of Aristotle's concept of virtue, including the distinction between intellectual and moral virtues and the role of the doctrine of the mean.
  • Contextualize further: Briefly situating the ergon argument within the broader context of ancient Greek philosophy or contrasting it with other ethical theories (e.g., Stoicism, Epicureanism) could add valuable depth.
  • Refine the conclusion: Ensure the conclusion not only summarizes but also offers a final, concise assessment of the argument's strengths and weaknesses or its lasting impact.
Applying the Ergon Argument to a Specific Virtue

Consider the virtue of courage. According to the ergon argument, courage is a virtue because it is a rational activity related to facing fear and danger. A courageous person does not simply act rashly (excess) or timidly (deficiency), but faces appropriate dangers for appropriate reasons and in appropriate ways, guided by rational assessment. This rational assessment involves understanding what is truly fearful and what is worth risking one's life for – a judgment informed by reason and cultivated through practice. Thus, courage isn't just a feeling or a single action, but a disposition to act rationally in specific circumstances, contributing to the overall excellent performance of the human function. The courageous individual demonstrates excellence in managing emotions (fear) and making rational judgments about risk, aligning their actions with the pursuit of the good life.
