Virtues in heaven

Here are two Aristotelian theses:

1. Complete human flourishing requires the exercise of all the human virtues.

2. Courage is a human virtue.

Add a highly plausible thesis that likely everyone will accept:

3. The exercise of courage requires apparent or real danger.

Now add some theses that a Christian will surely accept:

4. In heaven, there are no apparent danger.

5. In heaven, there is no real danger.

6. In heaven, there is complete human flourishing.

Contradiction!

I find it nearly impossible to deny 3-6. That leaves 1 and 2.

One move available to the Christian Aristotelian is to weaken 1. Perhaps complete human flourishing only requires the exercise of fundamental virtues, and courage is a non-central virtue. But traditionally fortitude also counts as a cardinal virtue, cardinal seems to imply fundamental, but fortitude is a virtue of dealing with evil—whether in the form of real or apparent danger, or of suffering, or of hardship, while there is no evil in heaven. So the problem comes back for fortitude. One solution is to deny the traditional cardinal virtues as being fundamental, and insist that the only fundamental virtue is love. Fortitude is just a central situational way for love to manifest.

Another move is simply to deny 1 altogether, of course, denying the whole link between virtues and flourishing. This is probably too radical.

And of course one might just deny 2. The most plausible move would be to say that only love is a virtue.

An ontological argument from justice

Buras and Cantrell have given a very clever ontological argument for the existence of God based on a desire for happiness. Here is a variant of their argument based on justice.

1. Ought implies (metaphysical) possibility.

2. There ought to be justice for humans.

3. Necessarily, if there is justice for humans, it is possible that there is a human who has happiness.

4. Necessarily, if there is a human who has happiness, God exists.

5. So, possibly God exists. (1-4 and S5)

6. So, God exists. (S5 and as God is essentially divine and necessarily exists.)

I want to expand a little on 3 and 4.

In any world where there is justice for humans, there is (a) a practical possibility of a human being innocent, and (b) a system that reliably rewards innocent humans with happiness. Items (a) and (b) taken together plausibly imply a practical, and hence metaphysical, possibility of happiness. That gives us (3).

Buras and Cantrell defend claim (4). My favorite defense of claim (4) is that human happiness, when we think through our deep desire for eternal life as well as the danger of boredom in eternal lfie, requires some sort of friendship with God.

A defense of natural law eudaimonism

My main objection to natural law ethics has for a long time been that it looks egoistic because it is eudaimonistic. One version of that worry is the “one thought too many” objection: You should just do good to your fellow humans because they are who they are, because they are your fellow human beings, or something like that, but definitely not because doing so leads to your flourishing.

I think there is a nice—and probably well-known to people other than me—response to this version of the worry, and to many similar “one thought too many” worries. To put this “one thought too many” worry more abstractly, the worry is that the metaethics will infect the reasons for action in an unacceptable way. But the response should simply be that, first, what metaethics asks is this question:

1. What makes the reasons for action be reasons for action?

Here, read “reasons” factively as “good reasons” or even “good moral reasons” (I don’t actually distinguish the two, but many do), not as motivations. And, second, insofar as R is my reason for my action, I am acting on account of R, not on account of R being a reason. Compare: what causes the fire is the match, not the match’s being a cause.

Thus, the natural lawyer should say that what makes the fact that an action promotes the good of my neighbor be a reason is that I flourish (in part) by intentionally (under this description) promoting the good of my neighbor. But the reason for the action is that the action promotes the good of my neighbor, not that I flourish by intentionally promoting the good of my neighbor. The natural law answer to the metaethics question (1) is this:

2. R is on balance a reason for action if and only if, and if so then because, I flourish by acting on R.

We do in fact flourish by intentionally promoting the good of our neighbor. Note that (2) does not by itself yield any egoism in our motivations. We could imagine selfless beings that flourish only insofar as they are intentionally promoting the good of their neighbor as a final end, and who are blighted insofar as they are intentionally promoting their own good or flourishing. We are, of course, not such selfless beings, but we don’t learn the fact that we are not such beings from (2). In fact, (2) is fully logically compatible with us being such beings. Hence, the metaethical theory (2) cannot by itself give rise to the “one thought too many” worry I started the post with. (Of course, some natural lawyers will go beyond (2). They may say that in fact our happiness is the end of all our actions. If so, then I think they are subject to the “one thought too many” worry.)

It is important to add a little bit to the above story. While it is true that “this benefits my friend” is typically reason enough, and that I don’t need to act on the second order fact that “this benefitting my friend is a reason”, we also do have such second order reasons. That there is a reason for an action is itself a reason for action. A parent might tell a child: “You have good reason to do this, but I can’t explain the reason right now.” In that case, the child could well be acting on the second-order reason that there is a first-order reason. (The child could also be acting on a first-order reasons to please the parent).

Here is another kind of case. I start off without any belief about whether R is a reason for action, and R leaves me cold. Maybe I am completely insensitive to considerations of privacy, and the fact that an action promotes someone’s privacy just leaves me completely cold. But I observe my virtuous friends, and see that they are acting on reasons like R, and I notice that their so acting contributes to what I admire about them. I conclude that R is in fact a good reason for action. But that’s purely intellectual. I am still left quite cold and unmotivated by the fact that some proposed action A falls under R. But what I can do at this point is to act on the second-order reason that A falls under a good reason. I can even say what that good reason is. But I cannot act on it itself, because it leaves me cold.

These are, however, non-ideal cases. If I know that R is a good reason, I should strive to form my will to be motivated by R. It will be better to act on R than to act on the knowledge that R is a reason. And thinking about these cases makes the response to the “one thought too many” worry about natural law even more compelling, I think. It does promote my flourishing to promote my flourishing, though I think that it doesn’t promote my flourishing as well as promoting the flourishing of others does. So that kindliness to others promotes my flourishing is a reason for benefiting others, just not as good a reason as that it benefits others. But such “not as good reasons” are important for our moral development: we are not yet in the ideal state, and so that “one thought too many” is still needed.

This helps make me feel a lot better about natural law ethics. Not quite enough to embrace it, though.

Well-being

Consider these statements:

1. Polluted air is bad for a tree.
2. Polluted air is bad for a ladybug.
3. Polluted air is bad for a mouse.
4. Polluted air is bad for a dog.
5. Polluted air is bad for a human.

As far as I know, these are all true. Moreover, it does not appear to me that "bad for" is used equivocally in all the cases.

Furthermore, the reasons for the truth of the items higher on the list remain in the case of the items lower on the list, but new reasons are added. Thus, pollution harms the growth and survival of a mouse just as it does a tree. But the mouse can get sick and feel pain, while the tree cannot. Thus, there is an additional reason for why pollution is bad for a mouse that does not apply in the case of the tree. And a human being can have various higher level goals be frustrated by pollution. However, the reasons for why polluted air is bad for a tree, a ladybug, a mouse or a dog are all reasons for why it is bad for a human as well.

This has obvious implications for a theory of human well-being. Since the reasons for why (1) is true have nothing to do with actual or counterfactual desires of trees, likewise, at least one of the reasons for why (5) is true obtains least in part independently of any actual or counterfactual desires of humans. And this shows that desire-fulfillment theories of human well-being are false: some things, such as health, are valuable for humans regardless of how humans feel about them, for the very same reasons for which they are valuable for trees.

The opponent will, I expect, either deny (1) and (2) (and maybe even (3)), saying that nothing is good or bad for trees or ladybugs, or else claim that I am equivocating on "bad for". Neither, though, seems that plausible.
