“To be playful is not to be trivial or frivolous, or to act as if nothing of consequence will happen. On the contrary, when we are playful… everything that happens is of consequence, for seriousness is a dread of the unpredictable outcome of open possibility. To be serious is to press for a specified conclusion. To be playful is to allow for unlimited possibility.”

“To come to know that nothing is good, nothing is bad, is a turning point; it is a conversion. You start looking in; the outside reality loses meaning. The social reality is a fiction, a beautiful drama; you can participate in it, but then you don’t take it seriously. It is just a role to be played; play it as beautifully, as efficiently, as possible. But don’t take it seriously, it has nothing of the ultimate in it.”

“We are most nearly ourselves when we achieve the seriousness of the child at play.”

“Serious art is born from serious play.”

“Play in curiosity is where everything happens.”

“[Waiting for Godot] has achieved a theoretical impossibility—a play in which nothing happens, that yet keeps audiences glued to their seats. What's more, since the second act is a subtly different reprise of the first, he has written a play in which nothing happens, twice.”
