“With peace and consolation hath dismist, And calm of mind all passion spent.”
The final chorus imagines calm after catastrophe as something reached through consolation and the exhaustion or resolution of violent passion, not as denial that death and grief have occurred.
Source note: Samson Agonistes, closing Chorus of Danites, in The Poetical Works of John Milton, Project Gutenberg #1745. The Chorus speaks after Samson’s death; the line is dramatic collective speech and is therefore kept separate from Milton’s personal voice.
