  In the book "Ferroelectric and Antiferroelectric Liquid Crystals" by S. T.
Lagerwall, the concept "polar liquid crystals" is proposed for the concept
earlier known as "ferroelectric liquid crystals", reserving the word
"ferroelectric liquid crystals" for the case of "surface stabilization". Thus
Lagerwall in this way, by redefinition, becomes the coinventor of
"ferroelectric liquid crystals". The trouble is that a closer look on the
invention reveals a state of bad logic and a total confusion. The concepts
"polar", "ferroelectric", "hysteresis", "SSFLC" and "bistability" are essential
in the writing of Lagerwall, but these words are not used in a rigorous way.
Also the pictorial evidence used by Lagerwall to illustrate the discovery of
surface stabilized liquid crystals raises several questions. An alternative
view of the physics of SSFLC cells is presented.
