Summary: Values pluralism and the grading of values.
Notice that there is a succession of things which can be considered as the kind of thing which is intrinsically good: from particular events of pleasure, to an individual's happiness, to an individual's eudaimonia, to the flourishing of a society, to the flourishing of an entire ecosystem. So it can be seen that there is a rather difficult problem about the scope of the theory of value. Where do you stop, in this succession of items, in your account of what is valuable for its own sake?
If you say that an individual pleasure is valuable for its own sake, then why don't you say that an individual's entire happiness is valuable for its own sake? And so forth: and on reaching the end of this sequence, we find ourselves valuing ecosystems which is itself an activity which seems metaphysical, inexplicable.
As a values pluralist, you might say: every item in this succession of items is intrinsically good. The goodness of a particular experience, of an individual's whole life, of society, and of an ecosystem, are all worth having for their own sake, and not merely as a means to something else. So as a values pluralist you would say: I don't have to decide which of these things is intrinsically good, because they are all intrinsically good.
That position does not seem to hold up to careful scrutiny. Sometimes we have a choice , for example, to sacrifice our own pleasure, or happiness, or even our own lives, for the sake of many other people. In these cases two things are weighed: your own individual happiness, and the more general happiness of a lot of other people. And if you conclude that you should sacrifice your own happiness, in one of these ways, what does that amount to?
It could say that your own life is worthwhile in and of itself, and that it is also worthwhile as a means to the happiness of others. Remember, the same thing can be both instrumentally and intrinsically good: understanding, or knowledge, is one possible example. It is clear that a human life might be another, and in that way some people would defend values pluralism. Two different things, a life and the good of society, can both be intrinsically good, even though one could be sacrificed for the second. This does not involve a contradiction.
Indeed, existentialism faces this dilemma in an egregious way: since being precedes essence, then our choices are paramount in setting our values. It makes little sense to evaluate one action over another: if they are real choices then they are expressions of our being, and of our ultimate freedom. Jean Paul Sartre faced the famous difficulty of being unable to decide whether it was better to stay at home to care for his elderly mother, or to go to war in the defence of his country.
We are left with an unresolved issue: the issue of the relative importance of intrinsic values. If these things are to be ranked in order of importance, how would the ranking go? So a person could be a values pluralist and still be an individualist, or a collectivist, or a radical environmentalist. It would just have to be said that the most important thing, the most valuable thing, is my own flourishing; or, instead, the flourishing of society; or, perhaps, the flourishing of the environment.
But this leaves us back at the start of the argument: on what basis do we, should we, choose in cases of conflict? Why is one thing better than another? Why is anything good?
Conclusion
After all this, we can see why the notion or thing called 'goodness' has a claim on being the most important, yet the most puzzling area of philosophy.
We can also see why there would be temptation to reduce values to prices, and why the value of Earth or value of life might be ultimately understood by economic methods, not ethical ones. To a degree, economics and ethics compete to explain people's choices. See also law and economics on this.
So much in our day to day life involves apparent value judgements: crucial life decisions we make, the habits we develop and transmit to our children, our deepest political convictions.
Academic philosophy seems to provide no objective criteria or decision process to help us in our decision making or reflections on these matters.
Hypothetical imperatives can outweigh Categorical imperatives, as we have seen, and intrinsic goods can be outweighed by instrumental goods. For each proposed ideal candidate for being called good, we seem able to envisage a situation where that candidate is judged bad.
Further, the prospect of the quest being successful, that goodness could finally be analysed, satisfactorily defined and universally agreed is unsettling for some people. They feel that perhaps the definition could be used in a totalitarian way, perhaps the world would lose some of its ambiguity, there may be a loss of diversity in society and in ways of life. So the fact that some existing choices may be threatened, produces the paradoxical situation that ultimate, incontrovertible knowledge of what is good may to some people not seem good or desirable.
Perhaps the only certainty we can have from looking at the investigations of philosopers over the centuries is that:
- What is good cannot be defined in abstraction from situations and our experience of them, academic approaches have so far proved infertile.
- There seems to be no enduring thing which can be said to be absolutely good in itself.
- Perhaps an inductive, empirical based investigation of goodness as the outcome of situations of valuation activity would be a more productive approach.
These conclusions may in the long run be more likely to give us some practical guidance in a world of multiple choice and of bewildering pluralism.
