Final Answer:
Glaucon classifies all goods into three categories: those desired for their own sake, those desired for both their own sake and their consequences, and those desired solely for their consequences.
Step-by-step explanation:
Glaucon's classification of goods aligns with his broader philosophical discussions in Plato's "Republic." First, goods desired for their own sake are intrinsic, representing values pursued for their inherent worth. Examples include pleasure, knowledge, and aesthetic experiences. Second, goods desired for both their own sake and consequences are instrumental.
These items, like wealth or power, are sought not only for their inherent value but also for the benefits they bring. Lastly, goods desired solely for their consequences are entirely instrumental, pursued only for the advantages they offer without any intrinsic value. Understanding these categories is essential to grasp Glaucon's views on morality and justice.
In the context of ethics, Glaucon uses these categories to discuss the nature of justice. He argues that people are naturally inclined to seek a balance between intrinsic and instrumental goods, pursuing both for a fulfilled life. This classification offers a framework for evaluating human motivations and choices, shedding light on the complexities of ethical decision-making. As Glaucon explores the interplay of these goods, he lays the groundwork for a nuanced understanding of virtue and the motivations behind human actions.
In summary, Glaucon's threefold classification provides a foundation for examining human desires and motivations. It distinguishes between intrinsic and instrumental goods, offering insights into the philosophical discourse on ethics and justice in Plato's "Republic."
