You can't talk about truth without talking about learning how to die because it's precisely by learning how to die, examining yourself and transforming your old self into a better self, that you actually live more intensely and critically and abundantly.
You have to have hope. It's irresponsible to give false hope, which I think a lot of playwrights are guilty of. But I also think it's irresponsible to simply be a nihilist, which quite a lot of playwrights, especially playwrights younger than me, have become guilty of.
