Yet reason dares her: No.

Mr. Upton,

Yet reason dares her—No,

which he explains thus: Yet, says Angelo, reason will give her courageNo, that is, it will not. I am afraid dare has no such signification. I have nothing to offer worth insertion.

IV.iv.28 (116,8)

[For my authority bears a credent bulk;
That no particular scandal once can touch]

Credent is creditable, inforcing credit, not questionable. The old English writers often confound the active and passive adjectives. So Shakespeare, and Milton after him, use inexpressive from inexpressible.

Particular is private, a French sense. No scandal from any private mouth can reach a man in my authority.

IV.iv.36 (116,9) [Nothing goes right; we would, and we would not] Here undoubtedly the act should end, and was ended by the poet; for here is properly a cessation of action, and a night intervenes, and the place is changed, between the passages of this scene, and those of the next. The next act beginning with the following scene, proceeds without any interruption of time or change of place.

IV.v.1 (117,1) [Duke. These letters at fit time deliver me] Peter never delivers the letters, but tells his story without any credentials. The poet forgot the plot which he had formed.
