Why public schoolboys like me and Boris Johnson aren’t fit to run our country

I remember the feeling of desolate homesickness: abruptly, several times a year, our attachments to home and family were broken. We lost everything – parents, pets, toys, younger siblings – and we could cry if we liked but no one would help us. So that later in life, when we saw other people cry, we felt no great need to go to their aid. The sad and the weak were wrong to show their distress, and we learned to despise the children who blubbed for their mummies. The cure was to stop crying and forget that life beyond the dormitories and classrooms existed. Concentrate instead on the games pitches and the dining hall and the headmaster’s study. By force of will we made ourselves complicit in a collective narrowing of vision.

In Richard Denton’s BBC documentary Public School, filmed at Radley College in 1979, the Radley headmaster Dennis Silk tells a daunted audience of new boys that they’re about to pick up “the right habits for life”. Among these habits was cultivation of the stiff upper lip. We could be ourselves – homesick, vulnerable, lovelorn and frightened – or, with practice at putting up a front, we could pretend to embody the idealised national character. We could perform being loyal and robust and self-reliant. Wearing a commendably brave face we could distance our feelings, growing the “hardness of heart of the educated”, as identified by Mahatma Gandhi from his dealings with the English ruling class.

This wasn’t healthy. In her 2015 book, Boarding School Syndrome, psychoanalyst Joy Schaverien describes a condition now sufficiently recognised to merit therapy groups and an emergent academic literature. The symptoms are wide-ranging but include, ingrained from an early age, emotional detachment and dissociation, cynicism, exceptionalism, defensive arrogance, offensive arrogance, cliquism, compartmentalisation, guilt, grief, denial, strategic emotional misdirection and stiff-lipped stoicism. Fine fine fine. We’re all doing fine.

In the early 80s, Radley’s non-teaching staff were known as College Servants. We had cleaners, chefs, groundsmen, bit-part players and comic mechanicals. They represented the proles, the plebs, the oiks, the yokels, the townies and the crusties (a term Johnson continued to use 40 years later). Our special language had its range of words to set these unfamiliar animals apart, meaning people not like us, and if you didn’t know the language you were probably one of them. As Orwell doubles-down in Nineteen Eighty-Four: “The proles are not human beings.”
