PURE AND APPLIED SCIENCE. 



»N speaking or thinking, a rUstinction is 

 often made between pure science and 

 applied science, without any real undent 

 standing of wherein the difference between them 

 exists, or on the other hand of the true relation between 

 the two. As Dr. Schuster put it, in an essay appearing 

 in Science Progress October 191ft, these two branches 

 of learning may best be considered as connected like.. 

 tlie branches of a tree to its stem. In tact, as hie' 

 remarks, the word science is equivalent to the word 



knowledge, and before knowledge can be appiiedl^ib 

 must e.\ist ; and knowledge by itself is not worth 

 much unless it can be applied to a given subject. 

 There is of course no antagoni.sni between these two 

 branches of knowledge, for on the one hand science 

 lies at the foundation of the development of all th* 

 conditions of human life, and on the other hand there 

 is something in science for which it deserves to be 

 cultivated, apart from its application in field or factory. 



Mere material comfort and wealth are probably 

 naturally the first aims of umnkind both as individuals 

 apd as societies ; but mental as well as bodily health 

 s to be also aimed at. Dr. Schuster puts the poinfc 

 excellently in his pre.sidential address to the British 

 Ajsooiation in 1&15, in the following sentence : ' the 

 duty to work, the right to live, and the leisure to 

 think are the three prime necessities of our existence, 

 and when one of them fails we only live an incomplete 

 life.' Just as applied science may be consideriHl to 

 conduce to the material prosperity of humanity, pure 

 science may be looked upon as ministering to its 

 mental welfare, in a manner not altogether unlike 

 artistic or literary pursuits. Besides, it has a special 

 value in this connexion, for science is continually 

 helping to the better knowletige of the laws of nature 

 which underlie the conditions of life, thus enabling 

 men to base their action on reason, rather than on 

 instinct or on the blind following of perhaps little 

 understood precedent?, and so it coaduces to mental 

 vigour. 



The distinction between pure and applied scieae* 

 would seem to be rather the mental attitude of the 

 worker than the degree to whicli the conchnions of
