Maslow defined Eupsychia as both a psychologically healthy culture and society.

Would a world of self-actualizers be like this utopia?

In Dostoevsky’s Crime and Punishment, main character Raskolnikov dreams of a hyper-individualistic culture. In this socioculture (or “culturiety”), each figure pursues their own morality. The dream ends with the collapse of society: it can’t be that everyone is their own ubermensch!

However, Eupsychia would presumably be more collaborative than Raskolnikov’s nightmare. People forge social contracts, defining a common ethics (law) based on intersubjective morality.

Perhaps Eupsychia consists in a kind of self-and-other-actualization. Self-actualization consists in becoming part of something greater than oneself, so perhaps it is sufficient. Still–in considering Nietzsche’s ubermensch who has overcome herd morality, along with Raskolnikov’s transgression–we must be mindful that the self actualizes for another.
