"I shall the effect of this good lesson keeps as watchman to my heart"
About this Quote
The phrasing “keeps as watchman to my heart” is the key dramatic move. A “lesson” isn’t private insight; it’s a disciplinary force, something learned the hard way in public, under consequence. Shakespeare’s characters rarely receive wisdom in a seminar. They get it through humiliation, betrayal, and near-ruin, then try to convert that pain into policy. The subtext is anxiety: if the heart is left unattended, it will relapse into appetite, jealousy, pride, or credulity - the engines of tragedy and the comic fuel of self-delusion.
The intent, then, is less sentimental than managerial. He’s dramatizing a person attempting to institutionalize regret, to turn a moment of clarity into permanent surveillance. That’s inherently ironic, because Shakespeare also knows the watchman can fall asleep. Conscience is unreliable; vows are theatrical; “lessons” fade when desire returns with better arguments.
Contextually, this kind of line fits his recurring post-crisis beat: after a moral shock, a character tries to narrate a new self into existence. It’s self-fashioning under pressure - the brittle hope that language can keep the heart from committing its next crime.
