> The traditional christian teaching is that solitude is bad. Man is a social animal and can only properly develop joined to family and community and church, fulfilling duties and obligations to each.
I wouldn't ascribe too much significance or meaning to 'Christian' teaching. It has no basis in science or empiricism.
And actually some quite important founders of Christianity (Jesus, Joseph) spent some time alone, in the desert and I don't think it's pictured as a 'bad' thing in the bible.
Psychology is a science, yes, and it holds that time spent alone is perfectly normal and for a large section of the population absolutely necessary for mental health.
