“Moreover, knowledge and investigation help promote wonder they do not destroy it. Whatever our tastes, we can generally appreciate such things as music, art or wine better when we understand a bit about them. We read up on our favourite singers or artists because we feel we can appreciate their work better when we know how they think and what they bring to their work. The giddy delight and curiosity that comes from marvelling at the beauty of this universe is deepened, not cheapened, by the laws and facts science gives us to aid our understanding. In a similar way, the psychological tricks at work behind many seemingly paranormal events are truly more fascinating than the explanation of other-worldiness precisely because they are of this world, and say something about how rich and complex and mysterious we are as human beings to be convinced by such trickery, indeed to want to perpetuate it in the first place.”

“Each of us is leading a difficult life, and when we meet people we are seeing only a tiny part of the thinnest veneer of their complex, troubled existences. To practise anything other than kindness towards them, to treat them in any way save generously, is to quietly deny their humanity.”

“There is a common response from people when they hear that in the absence of evidence to convince me otherwise I don’t have any particular belief in ghosts, psychic powers or an afterlife. It normally runs something along the lines of ‘So you think we just live, die and that’s it? Come on...’ There’s a clear implication there that this earthly life – the wonder of being human – is somehow worthless. That it’s cheap and disappointing enough to warrant that ‘just’ and the accompanying incredulous tone, which are usually reserved for sentences like ‘After all that it was just a little spider? Come on...’ I live, I am sure, in a fairly narrow band of life, and make an embarrassingly pitiful attempt to explore the world I find myself upon. I ache with guilt and conflict when I hear of people living as adventurers, abandoning mainstream lives and living each day with abandon. But I really hope I have a brighter vision for this life and a greater curiosity for its richness than one who can say, and mean, ‘You think we just live, die and that’s it?”

“Human existence is temporary and all the knowledge of the universe we acquire will in time be forgotten because there will be no humans left to benefit from any of the stuff we learned.And yet, this doesn't invalidate scientific exploration to me. We seek to understand the universe because it makes our lives better and more rich. Similarly, we tell stories (and think about why and how to tell stories) because it makes human existence richer. Made-up stories matter. They bring us pleasure and solace and nurture empathy by letting us see the world through others' eyes. They also help us to feel unalone, to understand that our grief and joy is shared not just by those around us but by all those who came before us and all those still yet to come.”

“There are times in our lives when we have to realize our past is precisely what it is, and we cannot change it. But we can change the story we tell ourselves about it, and by doing that, we can change the future.”

“The task of evolutionary psychology is not to weigh in on human nature, a task better left to others. It is to add the satisfying kind of insight that only science can provide: to connect what we know about human nature with the rest of our knowledge of how the world works, and to explain the largest number of facts with the smallest number of assumptions.”

“For me, I think the greatest achievements of science is to allow humanity to realize that our world is comprehensible. Through science, rational thinking, we can understand how the universe works.”
