“Walking: it hits you at first like an immense breathing in the ears. You feel the silence as if it were a great fresh wind blowing away clouds. There’s the silence of woodland. Clumps and groves of trees form shifting, uncertain walls around us. We walk along existing paths, narrow winding strips of beaten earth. We quickly lose our sense of direction. That silence is tremulous, uneasy. Then there’s the silence of tough summer afternoon walks across the flank of a mountain, stony paths, exposed to an uncompromising sun.”
