SCIENCE. 



[Vol. XVII. No. 419 



following passage, for instance, in Mr. Harris's work, can hardly 

 be called intelligible: "In the category of ground, or substrate, 

 says Hegel, ' the simple identity of essence is in immediate unity 

 with its absolute negativity.' That is to say: Reflection posits 

 identity and non-identity by relating to itself; its return is a self- 

 repulsion " (p. 333). If our readers can find a meaning in that, 

 they will do better than we can. 



As regards method and doctrine, the great blunder of Hegel, 

 as of some other Germans, consists in mistaking mere abstrac- 

 tions of thought for concrete realities, and this blunder is the 

 source of most of their peculiar doctrines. Moreover, the claim 

 put forth by Hegel and his followers, that their philosophy is all 

 deduced from pure thought, without any elements derived from 

 experience, is not in accordance with the facts. The idea of 

 thought itself is derived from experience, and so is that denoted 

 by the word '"pure." Then the ideas of being, quantity, quality, 

 relation, and others, which are essential data in Hegel's system, 

 are obviously got by experience; and thus the claim that his 

 philosophy is independent of experience cannot be allowed. 

 Happily, the Hegelian philosophy is already dead in the land of 

 its birth, and is rapidly dying elsewhere; and the feeble attempts 

 of certain Americans to galvanize it into life again are foredoomed 

 to failure. 



AMONG THE PUBLISHEES; 



The word "croup" carries such terror with it, and is applied to 

 so many conditions in infancy, that Dr. W. L. Carr's exhaustive 

 article on "Croup as a Symptom in Different Diseases," in the 

 February number of Babyhood, will be read with interest by 

 thousands of young mothers. A hardly less important topic is 

 treated by Dr. William H. Flint in his article on " The Causes of 

 Foul Breath in Childhood," which points out clearly the origin of 

 that annoying condition, and will be found of practical value. 



"A Short Talk about Ears," by Dr. W. K. Butler, is another 

 leading medical article. In a lighter vein are contributions on 

 such subjects as "Spoiling a Child," "Baby's Memory," "Nursery 

 Methods in Vienna," etc. 



— ' ' Across East African Glaciers " is the title Dr. Meyer has 

 given to his account of the first ascent of Mount Kilima Njaro, 

 one of the most important events of recent African exploration. 

 It will be published immediately in this country by Longmans, 

 Green, & Co. 



— We have received from the Open Court Publishint; Company 

 of Chicago a pamphlet by Alfred Binet, '• On Double Conscious- 

 ness," consisting of articles reprinted from the Open Court. The 

 introductory chapter is on the study of experimental psychology 

 in France, in which the author points oat that the school to which 

 he himself belongs have devoted themselves in the main to path- 

 ological psychology, or the study of the mind in abnormal states. 

 He then takes up the various phenomena observed of late years 

 which appear to him to show that there rnay be in a given indi- 

 vidual a double consciousness, or, as he sometimes expresses it, a 

 double personality. In support of this view, he recounts a num- 

 ber of curious experiments; but the reasoning by which he de- 

 duces from them his theory of double personality seems to us very 

 incautious and inconclusive. In particular, he constantly con- 

 founds personality with consciousness, — a mistake that could not 

 be made by any person trained in philosophy. M. Binet's experi- 

 ments will interest those engaged in similar researches, but his 

 theories should be accepted with great caution. 



— Mr. Charles F. Cox read a paper before the American Folk- 

 Lore Society in November last on " Faith-Healing in the Sixteenth 

 and Seventeenth Centuries," which has now been issued as a 

 pamphlet from the De Vinne Press, New York. The object of 

 the paper is to delineate some of the older forms of what is now 

 known as " Christian science," which were far more extravagant
