The simplicity of winter has a deep moral. The return of Nature, after such a career of splendor and prodigality, to habits so simple and austere, is not lost either upon the head or the heart. It is the philosopher coming back from the banquet and the wine to a cup of water and a crust of bread.

Burroughs treats winter not merely as a season but as an ethical lesson. After nature’s “splendor and prodigality” (the abundance and sensual richness of warmer months), winter’s austerity models restraint, humility, and a return to essentials. The image of “the philosopher coming back from the banquet” suggests that true wisdom is proven not in moments of plenty but in the ability to accept simplicity without resentment. The season’s bareness clears the mind (“head”) and steadies the emotions (“heart”), implying that deprivation can refine perception and character, and that cycles of abundance and scarcity are instructive rather than merely harsh.
