Perhaps what moves us most in winter is some reminiscence of far-off summer. How we leap by the side of the open brooks! What beauty in the running brooks! What life! What society! The cold is merely superficial; it is summer still at the core, far, far within. [. . .] I hear faintly the cawing of a crow far, far away, echoing from some unseen wood-side, as if deadened…It mingles with the slight murmur of the village, the sound of children at play, as one stream empties gently into another, and the wild and tame are one. What a delicious sound! It is not merely crow calling to crow, for it speaks to me too. I am part of one great creature with him; if he has voice, I have ears. I can hear when he calls. . .

— Henry David Thoreau
