Soul: the immaterial core of a person or community, often synonymous with “spirit”, which typically refers to that principle of organization which unifies its plurality of aspects as one and/or animates its life and agency.

In Aristotle, the active principle that produces life in a material being.

In underlying principle, the ultimate elective depth and reach of human feeling opening beyond self as felt bonds of being which admit of infinite possibilities which music, the arts, and religions variously express. Soul admits of measure of life value to the extent of its inclusion of other life and life ranges in resonance of fellow being.
