The one cause of their disturbance is that their "peculiar institution" of negro slavery is growing less and less secure — that they can neither extend it nor perpetuate it. Is this a reason to be alarmed? Is it not, rather, the best news that could possibly come to our ears?
Original passage & context
"Fortunately for us, the precipitation of South Carolina has produced a pause in our movements [...] The one cause of their disturbance is, that their "peculiar institution" of negro slavery is growing less and less secure, and that they see more and more reason to believe that they can neither extend it nor perpetuate it! Is this a reason for us to be alarmed? Is it not, on the contrary, the best news, with one exception, that could possibly come to our ears?"
Garrison — who had long wanted the free North out of "the Union with slaveholders" — reads South Carolina's exit as vindication, not alarm: the slaveholders panic because slavery "is growing less and less secure," which is "the best news... that could possibly come to our ears." Written against a conservative Boston address urging Massachusetts to make concessions to save the Union. "Negro" is the period term, not a redaction.
