in Thoreau’s Journal:

The last sunrise I witnessed seems to outshine the splendor of all preceding ones, and I was convinced that it behoved man to dawn as freshly, and with equal promise and steadiness advance into the career of life, with as lofty and serene a countenance to move onward through his midday to a yet fairer and more promising setting….We will have a dawn––and noon––and serene sunset in ourselves.
