On the Use of Masterpieces by Arthur Quiller-Couch

Masterpieces, then, will serve us as prophylactics of taste, even from childhood; and will help us, further, to interpret the common mind of civilisation. But they have a third and yet nobler use. They teach us to lift our own souls.

For witness to this and to the way of it I am going to call an old writer for whom, be it whim or not, I have an almost 18th century reverence -- Longinus. No one exactly knows who he was; although it is usual to identify him with that Longinus who philosophised in the court of the Queen Zenobia and was by her, in her downfall, handed over with her other counsellors to be executed by Aurelian: though again, as is usual, certain bold bad men affirm that, whether he was this Longinus or not, the treatise of which I speak was not written by any Longinus at all but by someone with a different name, with which they are unacquainted.
