What causes us to care for "the needs of the one," I submit, is the belief that together we comprise not simply "the many," but "the whole," or something like it. We acknowledge some basic common truths, values, and purposes. We see one another not as discrete organisms competing for scarce resources, but as diverse organs contributing to the good of a whole body, and finding joy and purpose in doing so. St. Paul famously said, when one member of a body suffers, all suffer; when one rejoices, all rejoice. Ben Franklin famously said, "We must all hang together; else assuredly we will all hang separately." Even the Three Musketeers famously chanted, "All for one, and one for all!"
