SOME BELATIONS BETWEEN PHILOSOPHY 



AND SCIENCE IN THE FIRST HALF 



OF THE NINETEENTH CENTURY 



IN GERMANY! 



I PRESENT this paper in response to Dr. 

 Councilman's request; and its choice of 

 topics is determined wholly by the instruc- 

 tions that he has given me in asking me to 

 prepare to meet you. It is not for me to 

 judge in what way these hastily prepared 

 notes can be of service to any of you ; and as a 

 fact, I confess myself unable to see that they 

 can be of any service whatever to a company 

 of pathologists. I am, of course, profoundly 

 ignorant of pathology. And, as I learn 

 from consulting the sources, the school of 

 scientific men of whom Virehow was the 

 leader felt, at the outset of their great 

 undertaking, in the years before 1850, that 

 philosophy, and, in particular, that what 

 used to be called, in Germany, the Natur- 

 philosophie, had formerly been, in the main, 

 profoundly harmful in its influence upon 

 medicine in general, and upon the begin- 

 nings of modern pathology in particular, 

 so that one great initial purpose of Vir- 

 ehow and of his allies, during the years 

 before 1848, was to free their young science 

 from whatever was still left of these evil 

 philosophical influences and to make it a 

 true natural science. I not only learn that 

 this was their opinion ; but I see, as any stu- 

 dent of the history of thought in the nine- 

 teenth century must see, that this opinion 

 was in a large measure very well justified.

 the Harvard Medical School, at the request of 

 Professor W. T. Councilman, President of the 

 Club.
