Bananas are great, as I believe them to be the only known cure for existential dread. Also, Mother Teresa said that in India, a woman dying in the street will share her banana with anyone who needs it, whereas in America, people amass and hoard as many bananas as they can to sell for an exorbitant profit. So half of them go bad, anyway.

I see that children fill the existential hollowness many people feel; that when we have children, we know they will need us, and maybe love us, but we don't have a clue how hard it is going to be.

Literature is my life of course, but from an ontological point of view. From an existential point of view, I like being a teacher.

Negro music and culture are intrinsically improvisational, existential. Nothing is sacred. After a decade, a musical idea, no matter how innovative, is threatened.

There's a real existential anxiety at having to exist not just in a generalised social framework, but a capitalist social framework.

Around the world, climate change is an existential threat - but if we harness the opportunities inherent in addressing climate change, we can reap enormous economic benefits.

There was an existential moment - I don't know if I want to call it crisis - when I turned 50 and I felt 'this is interesting; how did this happen?' It affected me in a way I wasn't expecting. It made me pause for reflection.

Huge public spending and borrowing in the face of an existential crisis is clearly the right thing to do, as is putting people's health and wellbeing above the pursuit of economic growth.

I was drawn to astronomy by a teenage existential quest. Around 13, I was deep into wondering about the meaning of life and what I was doing here. I turned to religion, but that did nothing for me. I got to wondering where was here. So, I began studying astronomy and became enthralled by what I learned.

I think that half of us feel fraudulent in our lives anyway. There's that strange disconnect of not really knowing what we're doing sometimes, or why it matters. It's our existential crisis.
