A good play is a play which, when acted upon the boards, makes an audience interested and pleased. A play that fails in this is a bad play. - Maurice Baring

Lord Saint-Edith said he couldn't understand people thinking Bacon had written Shakespeare's plays. If they said Shakespeare had written the works of Bacon as a pastime he could understand it.

Here's the lily, here the rose
Her full chalice shall disclose;
Here's narcissus wet with dew,
Windflower and the violet blue.
Wear the garland I have made;
Crowned with it, put pride away;
For the wreath that blooms must fade;
Thou thyself must fade some day,
Rhodocleia.

In Mozart and Salieri we see the contrast between the genius which does what it must and the talent which does what it can.
