Its great power is contested by none; rather, all recognise it, and many and violent are the disputes as to its right use and purpose.

I propose to consider two of the disputants--the propagandist playwright and the art-for-art's-sake artist, since they raise issues that are our concern.

It is curious that two so violently opposed should be so nearly alike in error: they are both afraid of life.

The propagandist is all for one side; the artist afraid of every side.

The one lacks imagination; the other lacks heart; they are both wide of the truth.
