On Start the Week Andrew Marr hears stories of virtue and vice. Lucy Bailey is directing Milton's Comus, a masque in honour of chastity, in which a Lady, lost in the woods, is tempted by pleasure. In Berg's opera Lulu the eponymous heroine appears to be the epitome of seductive pleasure, an amoral seductress, but William Kentridge's production questions how much she is the real victim. The academic Simon Goldhill charts the transition from the high Victorian period into modernity through one family's relationship with sex, psychoanalysis and religion, while the very modern preoccupation with therapy is laid bare, as Susie Orbach reveals what happens behind the therapist's door.
