<DIV>There exists an undeniable chasm between the capacities of humans and those of animals, but what exactly is the difference between our minds and theirs? In <I>The Gap</I>, psychologist Thomas Suddendorf provides a definitive account of what makes human minds unique and how this disparity arose. He proposes that two innovations account for all of the ways in which our minds appear so distinct: our open-ended ability to imagine and reflect, and our insatiable drive to link our minds together. It is not language or morality that set us apart, but the ability to consider a range of scenarios, real and imagined, past and future. A provocative argument for reconsidering our place in nature, <I>The Gap</I> is essential reading for anyone interested in our evolutionary origins and our relationship with the rest of the animal kingdom.</DIV>
