1 Well-Being

Well-Being
What is noninstrumentally good for a person

Theories of well-being attempt to tell us what makes a person’s life better or worse for them.

Synonyms and terms closely associated with well-being include:

  • welfare
  • personal-interest
  • self-interest
  • quality of life
  • eudaimonia
  • happiness
  • flourishing

Key Concepts

Instrumental Value
Something is instrumentally valuable if and only if it is valuable as a means to some other valuable thing.
It is good because of it’s consequences.
Final Value (non-instrumental value)
Something is finally valuable if and only if it is valuable as an end.
It is good “for its own sake.”
Prudential/Personal Value
Something is prudentially valuable for someone if and only if it benefits that person.

Glaucon on Well-Being Plato’s Republic

Glaucon on three kinds of goods:

How would you arrange goods—are there not some which we welcome for their own sakes, and independently of their consequences, as, for example, harmless pleasures and enjoyments, which delight us at the time, although nothing follows from them? … Is there not also a second class of goods, such as knowledge, sight, health, which are desirable not only in themselves, but also for their results? … And would you not recognize a third class, such as [exercising, receiving medical treatment, and working]—these do us good but we regard them as disagreeable; and no one would choose them for their own sakes, but only for the sake of some reward or result which flows from them?

   — Glaucon in Plato’s Republic 357b–d

Mere Final Value: Good for its own sake but not for its consequences

harmless pleasures and enjoyments
 

Final and Instrumental: Good for its own sake and its consequences.

knowledge, sight, and health
 

Mere Instrumental Value: Good for its consequences, but not for its own sake.1

exercising, receiving medical treatment, and working
 

Glaucon then ask Socrates to place justice in one of these three categories.

I want to know in which of the three classes you would place justice?

   – Glaucon in Plato’s Republic 357d

2 Well-Being and Justice

The Ring of Gyges

If you could imagine any one obtaining this power of becoming invisible, and never doing any wrong or touching what was another’s, he would be thought by the lookers-on to be a 40 most wretched idiot, although they would praise him to one another’s faces, and keep up appearances with one another from a fear that they too might suffer injustice.

   – Glaucon in Plato’s Republic 360d

The just life and the unjust life

After the story of Gyges, Glaucon describes two different lives:

  • a perfectly (entirely) unjust life
  • a perfectly (entirely) just life

What makes the unjust life good?Consequences
What what about just life?

Footnotes

  1. Glaucon says that goods in this category are “disagreeable.” However, something can merely instrumentally valuable (only good for its consequences) without being disagreeable. For example, I might take a pain killer to relieve my headache. Taking a pain killer is only valuable because of it effect, but I don’t find taking the pain killer disagreeable.↩︎
