Is this a dagger which I see before me,
The handle toward my hand? Come let me clutch thee:
I have thee not, and yet I see thee still.
Art thou not, fatal vision, sensible
To feeling as to sight? or art thou but
A dagger of the mind, a false creation,
Proceeding from the heat-oppressed brain?
I see thee yet in form as palpable
As this which now I draw
At school we had a system of black-marks (called ‘untidies’) which were meted out by senior girls who inspected common-rooms and cloakrooms daily just before tea. At the end of tea a senior would read out the list of miscreants - and their misdemeanours: a scarf left on the cloakroom floor, a writing-case left on the common-room table, a hockey-boot - not put away in a cloakroom locker.
These were to be reported to Group-leaders next lunchtime. (we had Groups rather than Houses - they had the embarrassingly twee names, Balmoral, Buckingham, Sandringham and Windsor.)
I usually managed two or three Untidies each term.
Oh dear, yet another. I mounted the stairs to the mezzanine where the mysterious pine-clad prefects’ study was, to report to a Buckingham Group Leader - we weren’t allowed to ask for specific people; one took pot luck This time I got the severest prefect, Carol M.
‘I’ve come to report an Untidy’ . I stood on the steps, trying to catch a glimpse of the inner sanctum.
‘Again? Which Shakespeare play are you studying in class? Macbeth? Right, bring your book to me after games..
Later I returned with ‘Macbeth’
She leafed through the book.
‘Right. I want you to learn this short passage off by heart. From ‘Is this a dagger…’ to ‘…this which now I draw’. By Wednesday.’
On Wednesday I made my way to the Study. …art thou not fatal vision.. bounded up the stairs ..or art thou but a dagger of the mind…and knocked on the door…the heat-oppressed brain..
I confronted Carol M. and handed her the book, opened at the marked page.
I took a deep breath:
‘IsthisadaggerwhichIseebeforemethehandletowardsmyhandcomeletmeclutchtheeIhavetheenotandyetIseetheestill.’
I closed my eyes to block out any distractions , and carried on, heady with my own success. I could see the end in sight:
‘…orartthoubutadaggerofthemindafalsecreationproceedingfromtheheat-oppressedbrain…proceedingfromtheheat-oppressedbrain….theheat-oppressed brain..’
But nothing more proceeded from my heat-oppressed brain. Nothing. Time seemed to stand still. I hardly knew where I was any more.
‘You may have another day - come back tomorrow.’
My brain melted with gratitude. I almost liked Carol M. now; after all, if she had chosen to she could have given me a completely new passage to learn.
I started down the stairs.
Proceeding from the heat-oppressed brain. I see thee yet in form as palpable as that which now I….I'd got it. I'd got it.

I remember those words 50 years later. And the many other poems and prose passages that I learnt ‘off by heart’ . I enjoy letting those words swim around in my head.
And I am grateful for that civilised ‘punishment’.
