It might seem bizarre to blame the murder of the French schoolteacher Samuel Paty on a nebulous conspiracy of leftist academics, given that the perpetrator, Abdoullakh Abouyedovich Anzorov, was an 18-year-old who had never been to university. But earlier this month in Le Monde, 100 French academics gave their backing to Jean-Michel Blanquer, the education minister, when he responded to the murder with a flood of invective against universities. ‘Islamo-leftism is wreaking havoc,’ he said. Paty’s murderer had been ‘conditioned by people who encourage’ a type of ‘intellectual radicalism’ and promote ‘ideas that often come from elsewhere’, i.e. from across the Atlantic. ‘The fish rots from the head,’ he added darkly. Blanquer was following the example of the president of the republic.
