Instead of bringing back 1600 plants, we might return from our journeys with a collection of small unfêted but life-enhancing thoughts.

Sweetness is the opposite of machismo, which is everywhere-and I really don't get on with machismo. I'm interested in sensitivity, and weakness, and fear, and anxiety, because I think that, at the end of the day, behind our masks, that's what we are.

What kills us isn't one big thing, but thousands of tiny obligations we can't turn down for fear of disappointing others.

I never wavered in my certainty that God did not exist. I was simply liberated by the thought that there might be a way to engage with religion without having to subscribe to its supernatural content - a way, to put it in more abstract terms, to think about Fathers without upsetting my respectful memory of my own father. I recognized that my continuing resistance to theories of an afterlife or of heavenly residents was no justification for giving up on the music, buildings, prayers, rituals, feasts, shrines, pilgrimages, communal meals and illustrated manuscripts of the faiths.

Everyone returns us to a different sense of ourselves, for we become a little of who they think we are.

William James once made an acute point about the relationship between happiness and expectation. He argued that satisfaction with ourselves does not require us to succeed in every endeavour. We are not always humiliated by failing; we are humiliated only if we first invest our pride and sense of worth in a given achievement and then do not reach it.

Perhaps it is true that we do not really exist until there is someone there to see us existing, we cannot properly speak until there is someone who can understand what we are saying in essence, we are not wholly alive until we are loved.
