Human beings have an astonishing evolutionary gift: agile imaginations that can shift in an instant from thinking on a scale of seconds to a scale of years or even centuries. The need to draw on our capacity to think long-term has never been more urgent, whether in areas such as public health care, to deal with technological risks, or to confront the threats of an ecological crisis. What can we do to overcome the tyranny of the now? The drivers of short-termism threaten to drag us over the edge of civilizational breakdown, while ways to think long-term are drawing us towards a culture of longer time horizons and responsibility for the future of humankind. Creating a cognitive toolkit for challenging our obsession with the here and now offers conceptual scaffolding for answering one of the most important questions of our time: How can we be good ancestors? ---Roman Krznaric Roman Krznaric is a public philosopher who writes about the power of ideas to change society.
