'The days of systems building, of repetition, and vulgarity elevated to the status of systematic discourse are definitely over. What is needed now is to start again, with rigorously one-sided class logic — courage and determination for ourselves, and detached irony towards the rest.'Mario Tronti, 'Lenin in England'
Another example for the rehabilitation of courage as a political virtue (plus irony). In case you should want an exercise in detached irony see Owen on Hazel Blears.
