Poor Will's Almanack for the third week of Early Winter.
In one of Aldo Leopold’s journals, that famous naturalist observed that the rate at which solar energy flows to and through living things not only affects the rate at which plants sprout, grow, flower, and die, but might also have some influence over human lives and the course of human events.
Seasonal affective disorder, a recently named malady that appears to be tied to a lack of sunlight, is one example of an event in human physiology that is tied to solar intensity.

Two thousand years ago, the Roman naturalist, Pliny praised the cold northern winds as the "healthiest of all."
During the eighteenth century, physicians said the same thing. For example, William Currie wrote that "the winds which prevail during the greatest part of winter… though they are severe and piercing cold...give vigor to the constitution and a freshness and bloom to the complexion."

When I read the journals of the naturalist Henry David Thoreau for the first time, I wanted him to tell me more about himself. I thought that all his notes on the thickness of ice at Walden Pond or about the dates the asters bloomed were frivolous.
I wanted him to talk, just once, about his most secret passions. I wanted him to stop hiding behind nature.
