Complexity (logical depth) as a measure of value. Advantage: Nicely attributes value to literature, cultural artifacts, evolved genomes, ecosystems, species, and complex thoughts and emotions (treated in an utterly materialist way, as patterns of atoms in people’s brains). Destroying the last copy of a good book, or the last individual of a species or human culture, is especially bad, because it destroys complex information not available elsewhere. In many cases such losses are prevented by biological and cultural replicative processes. Even a major asteroid impact would probably not destroy all copies of Shakespeare’s works, of the human genome, or all Model-T Fords.
Problem: scaling with number: we would like to believe that many people’s happiness is not like many copies of a good book, scarcely more valuable than one copy. Possible answer: People’s experiences are so different that they hardly overlap. An adolescent, on falling in love for the first time, thinks “I am the first person ever to feel this”. We elders smile. But for other kinds of experience it probably really is true. For example I find that my friends are all different, enriching and complicating my life in ways that overlap only slightly from one friend to another.
