Sonnet 141 is one of several poems in the collection that show William Shakespeare to be deeply ill at ease with his lust and his love for his mistress.

It may easily be argued that all of the Dark Lady Sonnets come over with a greater or lesser degree of ambiguity, with her appearance, her comportment, her smell, her touch, her sound, and most certainly her fidelity, all having either been brought into question or downright decried.

Sonnet 141 does all of the above, summarising these 'thousand errors' his mistress appears to possess and laying them out as a supposedly sensual feast, the like of which he has no appetite for. Yet he still finds his foolish heart drawn to her, and for this, he concludes, he must suffer the pain that he appears to accept as his – perhaps in a somewhat perverse way – due reward.

In this special episode, Phyllis Rackin, Professor Emerita of English from the University of Pennsylvania in Philadelphia and former president of the Shakespeare Association of America talks to Sebastian Michael about the position of women in Elizabethan society, about William Shakespeare's relationship with the women in his life, and about what we can and cannot know specifically of the Dark Lady in his Sonnets.

With Sonnet 140, William Shakespeare at first seems to set out on some general counsel for his mistress not to try his patience too much, as doing so might drive him mad and cause him, in his madness, to say bad things about her. The damage this could do would be exacerbated by a world that is itself full of mad people who would be inclined to believe him even if what he came out with were but scurrilous lies.

Strongly implied also though is that not everything scandalous he might say about his mistress would necessarily be untrue, And with the last line of the closing couplet, he then ties his sonnet firmly back to the previous one and reiterates his request that even though she obviously has other lovers, she keep her eyes on him when they are together at least.
