by Franz Carl Muller-Lyer (Author)
So many books on marriage leave one with a feeling of chaos that it is important to examine any document underlying the discovery of order by searching for underlying tendencies.
The author emphasizes the necessity of taking the evolutionary point of view, and sees in militant feminism, which teaches emulation of men, a phase which will pass as women come to make their own peculiar spiritual contribution to civilization as men have done. Perhaps this will come the sooner, he suggests, if women will regard themselves as the equivalents and not as the equals of men.
Author Biography
Franz Carl Müller-Lyer, born Francis Xavier Hermann Müller (5 February 1857 - 29 October 1916) was a German psychologist and sociologist. The Müller-Lyer illusion is named after him.
Müller-Lyer was born in Baden-Baden. He studied medicine at the Universities of Strasbourg, Bonn, and Leipzig. He also studied psychology and sociology at the Universities of Berlin, Vienna, Paris and London.
In 1888 he entered into private practice in Munich.
The optical illusion he described in 1889 involves the perception of the length of a line when the ends are capped by chevrons. Diverging chevrons seem to make the line longer when compared with converging chevrons. There are numerous similar geometrical illusions known now.
