Answer:
Light, line, and color as sense-related pleasures, came later and were as crude as the rest.
Explanation:
The quotation that provides further evidence for the claim that the Bostonian developed a double nature is:
"Light, line, and color as sense-related pleasures, came later and were as crude as the rest." (paragraph 2)
This quotation suggests that the Bostonian experienced a duality in their perception and appreciation of life. While they may have initially focused on more basic, practical aspects of life represented by "crude" elements, such as the cold grays of November evenings and the thick, muddy thaws of Boston winter, they eventually developed an appreciation for more aesthetic and sensory experiences, such as light, line, and color. This evolution in their perception indicates a double nature or dual perspective on life.
