in Thoreau’s Journal:
The winter with its snow and ice is not an evil to be corrected…..To perceive freshly, with fresh senses, is to be inspired. Great winter itself looked like a precious gem reflecting rainbow colors from one angle. My body is all sentient. As I go here or there, I am tickled by this or that I come into contact with, as if I touched the wires of a battery. I can generally recall, have fresh in my mind, several scratches last received. These I continually recall to mind, reimpress and harp upon. The age of miracles is each moment thus returned; now it is wild apples, now river reflections, now a flock of lesser red-polls. In winter, too, resides immortal youth and perennial summer….
What if we could daguerreotype our thoughts and feelings !
