• That great Irish prophet of Brexit, William Butler Yeats, put it thus: “The best lack all conviction while the worst are all passionate intensity.” That the centre may not hold is the nightmare that Europe must not dismiss.

• Shame to omit the original poll tax protester (Stripped: a history of nude protests, G2, 3 April): Lady Godiva.

• Perhaps James Corden should have tried opera (Larger actors miss out on romantic roles, says James Corden, 2 April). On Saturday we saw a very large Siegmund kissing and cuddling with Sieglinde. But he would need the right voice: I remember the bass-baritone Ian Wallace on Radio 4’s My Music saying ruefully “the tenor always gets the girl”.

• Martyn Thomas asks how we could tell if AI had developed consciousness (Letters, 4 April). An Edinburgh University students’ magazine in 1973 answered this question in a two-frame cartoon. In the first frame a boffin presses his robot’s on switch to set it to work. In the second frame the robot presses its off switch.
