It's an odd thing about this universe that, though we all disagree with each other, we are all of us always in the right.

With dry, epigrammatic irony, Smith points to a common human bias: each person experiences their own beliefs as self-evidently correct, even when those beliefs collide with others’. The “odd thing” is not that people disagree, but that disagreement rarely weakens certainty; instead, conviction tends to be reinforced by temperament, self-interest, and selective attention. The line satirizes the way “rightness” often functions less as an objective conclusion than as a psychological stance. In a broader sense, it hints at the social difficulty of achieving genuine understanding: if everyone feels “always in the right,” conversation becomes less a search for truth than a contest of perspectives.
