Blaisdell—The Methods of Science , 
this same reason imposes on things their identities as law not 
only of their place in a reasonable system but of our thought of 
them as having that place in a reasonable system. To think of 
the facts with which chemistry deals, having in a certain view 
a communicant identity, as having some other identity and 
being part of another territory, confounding thus the territories 
of fact into which the universe is divided, is to think illogi- 
cally, because logic requires that science think things as they 
are. It appoints to some one science to make report of a given 
range of the system and gives its orders that others do their 
office within that in inferior scope so as to be subordinate, and 
others still further subordinate, and others still further sub¬ 
ordinate, each according to some real natural organic division of 
the larger field. Another range it assigns to another science. 
To the great imperial sciences it will be given to occupy co-ordi¬ 
nate service including these lower, and, as these higher must be 
subordinate to the highest, to that highest and supreme science 
will belong the prerogative of making the whole universe the field 
of its study. In this manner each science will be required to 
occupy its several exact place. Nor will empirical observation 
have the last word in thus distributing the fields of the various 
sciences, for this can only be determined by penetrating to the 
heart of the great system and ascertaining the order and reason 
in which is all its significance and from which all derives its 
wonderful form. Behind all empirical determinations the dis¬ 
tribution of the sciences will be in subjection to that deeper 
project. Unexpected sciences come into being subordinating 
what seems to be supreme, casting down what is lifted up and 
lifting up what was cast down. Reason thus being ground in 
which all things have their existence and being the ultimate 
truth, science, by the insistence of logic, subjects her service to 
the law of sufficient reason. 
3. Logic gives law to the methods in which science prosecutes its 
special individual procedures. We hear much of the methods of 
science and of the scientific habit of mind, as if there were some 
directive of mind in its taking possession of its domain which it 
were well to form the habit of complying with. If I mistake 
not logic furnishes the ultimate canon for such directive.
