Peter Ulric Tse is professor of Psychological and Brain Sciences at Dartmouth College in New Hampshire, USA. His lab looks into the cognitive and neural processes behind our visual perception, attention, consciousness and, recently, the brain activity involved in imagination. The results of his studies suggest that ‘imagination’ is a process which takes place across both sides of the brain, in numerous different regions across the neural network.

Arundhathi Subramaniam is the author of four books of poetry, most recently When God is a Traveller. Her prose works include the bestselling biography of a contemporary mystic, Sadhguru: More Than a Life, and The Book of Buddha. As editor, she has worked on anthologies of essays on sacred journeys in the country, contemporary Indian love poems in English and a book of Bhakti poetry, Eating God.

Noel B. Salazar is Research Professor in Anthropology at the University of Leuven. His research interests include anthropologies of mobility and travel, the local–global nexus, discourses and imaginaries of Otherness, heritage interpretation, culture contacts and cosmopolitanism. He is the author of Envisioning Eden: Mobilizing Imaginaries in Tourism and Beyond.

Noel Salazar says that we should walk more: people walk to relax, to exercise, to complete a pilgrimage. Some also walk to think or to stimulate their imagination. Many of history’s great philosophers and writers recognized the benefits of ambulation. So why not generalize walking as a principal method of education and instruction, from preschool onwards? It might stimulate the imagination and creativity that is so desperately needed to solve the world’s problems. And it is much more fun than sitting around a table to ‘brainstorm’ about the next great idea.
