CONSCIOUS AND UNCONSCIOUS KNOWERS. 31 



not inaptly with the two main parties into which the 

 political world is divided. The one class is deeply 

 versed in those sciences which have already become 

 the common property of mankind ; enjoying, enforcing, 

 perpetuating, and engraining still more deeply into the 

 mind of man acquisitions already approved by common 

 experience, but somewhat careless about extension of

 is chiefly intent upon pushing forward the boundaries 

 of science, and is comparatively indifferent to what is 

 known already save in so far as necessary for pur- 

 poses of extension. These last are called pioneers of 

 science, and to them alone is the title " scientific " 

 commonly accorded ; but pioneers, important to an army 

 as they are, are still not the army itself, which can get 

 on better without the pioneers than the pioneers with- 

 out the army. Surely the class which knows thoroughly 

 well what it knows, and which adjudicates upon the 

 value of the discoveries made by the pioneers — surely 

 this class has as good a right or better to be called 

 scientific than the pioneers themselves. 



These two classes above described blend into one 

 another with every shade of gradation. Some are ad- 

 mirably proficient in the well-known sciences — that is 

 to say, they have good health, good looks, good temper, 

 common sense, and energy, and they hold all these good 

 things in such perfection as to be altogether without
