"An idea of art opposed to the idea of utility, an idea of an audience opposed to the idea of popularity, an idea of the peripheral becoming the central culture – in these three ideas Yeats provided Irish writing with a programme for action. But whatever its connection with Irish nationalism, it was not, finally, a programme of separation from the English tradition. His continued adherence to it led him to define the central Irish attitude as one of self-hatred... The pathology of literary unionism has never been better defined."
January 1, 1970
