"It is not charity but a right, not bounty but justice, that I am pleading for. The present state of civilization is as odious as it is unjust. It is absolutely the opposite of what it should be, and it is necessary that a revolution should be made in it. The contrast of affluence and wretchedness continually meeting and offending the eye, is like dead and living bodies chained together.
…
[I]t ought not to be left to the choice of detached individuals whether they will do justice or not."
Thomas Paine, quoted at length in John Nichols’s The “S” Word.
