Our thoughts are social constructions. Language is a tool which enables us to name things, describe the context for those things, create a storied history of our experience and relationship with those things, and these activities, usually unconsciously engaged in, is a social not an individual activity.
No person is an island. The American idea of rugged individualism is a big lie. There is no such thing. We are all joined in a social fabric and the idea that we are separate individuals is a trick of the ego which creates hell on earth.
Unitarian Universalists know this because when they covenant together to affirm and promote the respect for the interdependent web of all existence they acknowledge this spiritual fact that we are not alone in experiencing the effects of our seeing.
