The youngest children have a great capacity for empathy and altruism. There's a recent study that shows even 14-month-olds will climb across a bunch of cushions and go across a room to give you a pen if you drop one.

Scientists learn about the world in three ways: They analyze statistical patterns in the data, they do experiments, and they learn from the data and ideas of other scientists. The recent studies show that children also learn in these ways.

Babies and young children are like the research and development division of the human species, and we grown-ups are production and marketing.

All of us gardeners know that nothing comes out the way you planned. It's a different garden every year, and it's always sort of different from what you were thinking when you began. What it really means to be a good gardener is to work hard to produce an ecosystem that will have enough diversity, enough possibilities, so it's robust, and it's resilient, and it can change when the seasons change. And that kind of robust, unexpected, variable, messy system - that's what you want to create when you're having children, too.

Adults often assume that most learning is the result of teaching and that exploratory, spontaneous learning is unusual. But actually, spontaneous learning is more fundamental.

We pass our values, ideas and moral character on to our children, but we do that knowing that our children are going to revise our knowledge and reshape their values. There's something very paradoxical and profound about being a parent as opposed to parenting. We put in all this effort and energy not so that we can shape a child of a particular sort, but so that all sorts of possibilities can happen in the future.
