I talk about very serious human affairs but with a lightness of heart.

Stupid is a great force in human affairs.

Language is a weapon of politicians, but language is a weapon in much of human affairs.

I'm sorry, I'm absolutely convinced that there is at the moment no realistic prospect for very much hope in human affairs.

Violence is never a solution in my plays, just as ultimately violence is never a solution in human affairs.

In all human affairs there are efforts, and there are results, and the strength of the effort is the measure of the result.
