“There is a different feel to another period in time that’s so basic it’s hard to describe,” Hubbard’s top US executive, Helen O’Brien, recalled. “If you find yourself in a room, there may be color with unfamiliar tones because of gaslight shining on it. The air has a strange quality. Its particles of dust derive from unmodern constituents. Even human bodies seem to radiate a different kind of warmth when they are covered with the fabrics of another age. Memory, per se, filters out all that. When you return, you find the past intact.”
