Unweaving the Rainbow This pleasure was not in spite of, but rather because he does not assume as cause the inexplicable actions of a deity but rather the understandable laws of nature. His starting point is John Keats' well-known, light-hearted accusation that Isaac Newton destroyed the poetry of the rainbow by 'reducing it to the prismatic colours.' Dawkins's agenda is to show the reader that science does not destroy, but rather discovers poetry in the patterns of nature. It is of little concern whether or not science can prove that the ultimate fate of the cosmos lacks purpose: we live our lives regardless
Rainbow by any water droplets viewed from a certain angle relative to a light source. Thus, a rainbow is not an object and cannot be physically approached. Indeed, it is impossible for an observer to see a rainbow from water droplets at any angle other than the customary one of 42 degrees from the direction opposite the light source. Even if an observer sees another observer who seems "under" or "at the end of" a rainbow, the second observer will see a different rainbow—farther off—at the same angle as seen by the first observer. Rainbows span a continuous spectrum of colours.
