Because it needs to be acknowledged on occasion, Christopher Hayes:

Sublime solidarity… embodies a powerful moral aspiration to realize the fundamental fellowship of humankind. The human subject imbued with full solidarity would treat each person the same way she would treat the interests of her closest kin. My father, a community organizer and one-time Jesuit seminarian, explains why solidarity is his favorite word by sketching a continuum that ranges from pearl-clutching pity through sympathy and empathy to arrive finally at solidarity, wherein you are propelled to do something for your fellow human beings, to act as if their interests were your own.

It is this solidarity Jane Addams described as “not philanthropy nor benevolence, but a thing fuller and wider than either of these,” and what Gandhi referred to when he spoke of the “essential unity of all people.”
