True Kindness is featured in Thoreau's collection, Poems of Nature (1895). We are impressed with his rhyming selection for "affinity." "Consanguinity" is "blood relation" in Latin; its root "sanguine" means optimistic or positive, a clever double entendre.
True kindness is a pure divine affinity,
Not founded upon human consanguinity.
It is a spirit, not a blood relation,
Superior to family and station.
