Happiness, friendship and eternity

When one is not tired of a friend, the expected approaching loss of union with the friend makes one miserable. To be tired of a friend would not be compatible with full human happiness, and neither would it be compatible with full human happiness to have no friends. Full human happiness is grounded in truth—it is not full happiness when one's delight depends on ignorance. Therefore, when one is not tired of a friend, an approaching loss of union with the friend one is not tired of is not compatible with full human happiness, whether the loss is expected or not. But neither is it compatible with full human happiness to be tired of friends or lack them. Thus, in full human happiness, one never approaches the loss of union with a friend. But if one were to cease existing, one would thereby lose all union with one's friends.

It follows that full human happiness requires unending life with at least one friend. Moreover, it requires a well-grounded security in this unending life (this point I learned from Todd Buras).

We can conclude from this that naturalism is false if we add the premises:

1. People have a natural desire for full human happiness.
2. What people have a natural desire for is possible.
3. If naturalism is true, then it is not possible to have well-grounded security in unending life.

One might think this argument can be simplified by arguing that if naturalism is true, unending life is impossible. But if the universe goes on expanding forever and quantum indeterminism holds, unending life is not impossible, just highly improbable (it gets less and less probable as the universe gets colder and colder). But such an unending life is insecure because of the improbability of its continuation.
