Attraction To Light
Moths frequently appear to circle artificial lights, although the reason for this behavior remains unknown. One hypothesis advanced to explain this behavior is that moths use a technique of celestial navigation called transverse orientation. By maintaining a constant angular relationship to a bright celestial light, such as the Moon, they can fly in a straight line. Celestial objects are so far away, that even after travelling great distances, the change in angle between the moth and the light source is negligible; further, the moon will always be in the upper part of the visual field or on the horizon. When a moth encounters a much closer artificial light and uses it for navigation, the angle changes noticeably after only a short distance, in addition to being often below the horizon. The moth instinctively attempts to correct by turning toward the light, causing airborne moths to come plummeting downwards, and resulting in a spiral flight path that gets closer and closer to the light source.

“The satirist is prevented by repulsion from gaining a better knowledge of the world he is attracted to, yet he is forced by attraction to concern himself with the world that repels him.”
—Italo Calvino (1923–1985)
“The great attraction of fashion is that it diverted attention from the insoluble problems of beauty and provided an easy way—which money could buy ... to a simply stated, easily reproduced ideal of beauty, however temporary that ideal.”
—Theodore Zeldin (b. 1923)
“Men’s hearts are cold. They are indifferent. Not all the coal that is dug warms the world. It remains indifferent to the lives of those who risk their life and health down in the blackness of the earth; who crawl through dark, choking crevices with only a bit of lamp on their caps to light their silent way; whose backs are bent with toil, whose very bones ache, whose happiness is sleep, and whose peace is death.”
—Mother Jones (1830–1930)
