308 FRAGMENTS OF SCIENCE 



perience of the true votary of science. And if a man 

 be not capable of this self-renunciation this loyal sur- 

 render of himself to Nature and to fact he lacks, in my 

 opinion, the first mark of a true philosopher. Thus the 

 earnest prosecutor of science, who does not work with

 man of science as a heroic, if not indeed an angelic, char- 

 acter; and cases may occur to you which indicate the re- 

 verse. You may point to the quarrels of scientific men, 

 to their struggles for priority, to that unpleasant egotism 

 which screams around its little property of discovery like 

 a scared plover about its young. I will not deny all this; 

 but let it be set down to its proper account, to the weak- 

 ness or, if you will to the selfishness of Man, but not 

 to the charge of Physical Science. 



The second process in physical investigation is deduc- 

 tion, or the advance of the mind from fixed principles to 

 the conclusions which flow from them. The rules of logic 

 are the formal statement of this process, which, however,
