Blinkered university

SIR – I read of the trigger warning for Petrushka at the University of Aberdeen with dismay (“Trigger alert for ‘distressing’ on-stage death... of a puppet”, report, January 13).

I recall discovering Petrushka as a child, hearing it on a Proms radio broadcast quite by chance. That inspirational experience was vital for me in developing a knowledge not only of ballet, opera, art and music, but also of world cultures. Surely educational life on any level – but especially at university – should encourage a spirit of open-minded discovery, not one of blinkered apprehension.
