Quis est homo qui non fleret? Who is the human who would not weep, at the sight of such great suffering? It’s the reverberant question posed by the Stabat Mater, a medieval poem and hymn that’s still perhaps the most famous account of the watching of suffering. In answer to it is an initial modern confusion: Today, we do a lot of affinity weeping. Living as so many do on our social media platforms, we’ve seemingly developed a discomfiting capacity to want to claim the dividends of a tragedy not our own, as our own.
