 THE POPULAR CONCEPTION OF THE SCI- 

 ENTIFIC MAN AT THE PRESENT DAY.^ 



We are so accustomed to hear reports on 

 the progress of science that we have almost 

 ceased to ask ourselves what we mean by 

 progress. "What is or is not progress de- 

 pends of course on the point of view. 

 Some are so far ahead of the majority that 

 they can not see how much progress is 

 made by those behind them; others are so 

 far in the rear that they can not distinguish 

 what is going on ahead of them. We must 

 also admit that there are different direc- 

 tions in which progress may be made. You 

 have all seen the agile crab and been sur- 

 prised to find how rapidly he gets over the 

 ground, although he never seems to go 

 ahead, but to scramble off sideways. The 

 crab, perhaps, wonders why men are so 

 stupid as to try to move straight forward. 

 It is a popular belief, but, not being a zool- 

 ogist, I am not prepared to vouch for its 

 correctness, that the squid progresses back- 

 ward, discharging a large amount of ink. 

 One might perhaps ask: Is the progress of 

 science sometimes like that of the crab, 

 rapid but not straight forward, or, like 

 the squid, may not the emission of a large 

 amount of printer's ink really conceal a 

 backward movement ? So far as the accu- 

 mulation of facts is concerned, there is a 

 steady onward progress in science and it is 

 only in the unwise or premature theorizing 

 on known or supposed facts that science
