Note 90 — THE MONIST.
Reading edition
“Light affects the new-born infant at an early stage, although in this as in other respects individual differences immediately assert themselves. The child seems to take pleasure in an excitation of light and tries (even on the second day after birth) to turn towards it in order to retain it.” (Outlines of Psychology, H. Höffding, p. 4.)
“Under the influence of light the conversion of inorganic matter into more complex organic matter takes place, more particularly in the green cells of plants.” (Ibid., p. 315.)
“It is certainly necessary to look further back than the visual sensations to understand the great influence of light on all creatures that have sensuous perception.... Light is thus one of the most elementary conditions of life.” (Ibid., p. 229.)
