Courage

'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.
