SEX 



THE WOMAN A MAN MARRIES 

 By Victor C. Pedersen. George H. Doran Co. 

 $3 .00 5! x 8|; x + 2.76 New York 



This is a realistic and mostly sound 

 discussion of sex relations in married life 

 by a physician. The point of view is to 



"treat of ignorance of biology and physiology, of 

 social development and social conditions, of marriage, 

 of venereal disease, and of the restoration or relief of 

 the whole complex difficulty as fully as possible and 

 as minutely as is wise for the purpose. Despite 

 research and reading for many years in this field, I 

 know of no other work which examines or aims to 

 examine the relation of the so-called virtuous woman 

 to the whole sexual problem. Very few persons in 

 my experience, though careful thinkers, realize that 

 women with misguided impressions of sex really 

 live according to a double standard which is equally 

 destructive of social and moral stability as the man's 

 double standard. The effect of their double standard 

 is that soon rather than late, and in high rather 

 than low degree, they violate the marriage con- 

 tract, because they enter into it under the pretense 

 of normal, complete love and then reveal themselves 

 as bereft of natural physical attachment without 

 which the whole marriage soon disintegrates. The 

 single standard for woman is to decide before marriage 

 that all its obligations are acceptable to her and 

 then proceed to live happily with her husband accord- 

 ing to them. Like all other contracts marriage does 

 not permit 'change of mind.' " 



The author is opposed to birth control, 

 except for certain definite medical reasons. 

 At the same time the book has much to 

 commend it. 



LOVE AND MORALITY. An Attempt 

 at a Physiological Interpretation of Human 

 Thought. 



By Jacques Fischer. Alfred A. Knopf, Inc. 

 $3-5° 5I x 8, x + Z91 New York 



A strange speculation, which starts by 

 elaborating the thesis that the combined 

 lipoids of the brain provide the causal 

 basis and mechanism for its intellectual 

 activities, and ends with a biochemical 

 defense of homosexuality. In between 

 is a lot about sex and morality and some 

 biochemistry. The book is certainly orig- 

 inal and is well-written, but the central 

 thesis of it all wants a great deal more 

 evidence in its support than can now be 

 adduced, before the author's wide-ranging 

 deductions can be taken seriously.

MATHEMATICAL STATISTICS. The 

 Carus Mathematical Monographs No. 3. 

 By Henry Lewis Riet%. 



Open Court Publishing Co. 

 $2.. 00 5 x 7I; xi + 181 Chicago- 



An excellent little treatise, which puts 

 its emphasis on the underlying mathe- 

 matical theory of modern statistical 

 methods rather more heavily than upon 

 the practical applications and computa- 

 tions. It will, on this account, serve as a 

 useful supplement to the elementary sta- 

 tistical manuals now in use.
