CARDINAL PRINCIPLES OF SCIENCE I I 



allelism between Man and Nature expresses a unity of the 

 human mind imposed by some extraneous power ; but the later 

 researches indicate that the relation varies with the degree of 

 cultural development — /. <?., that savage minds respond nearly 

 alike to like stimuli, that all barbaric minds are measurably 

 similar in their responses to environmental stimuli, that civi- 

 lized minds work in largely similar ways under similar condi- 

 tions, and that all enlightened minds are alike in their efforts to 

 dominate nature, but that minds of the different culture grades 

 do not respond alike — and hence that the interaction itself con- 

 forms with the lines of serial development characteristic of the 

 inorganic and organic realms of nature. Accordingly the pres- 

 ent-day anthropologist is in a position to at least provisionally in- 

 tegrate the sum of experiences concerning intellectual mankind 

 in a formula expressing the interrelation of psychic and non-psy- 

 chic interactions. The formula may be framed in conscious 

 accordance with the Baconian platform which so well (albeit so 

 unwittingly) served to support the earlier principles, and in con- 

 formity with these it may be phrased The Responsivity of Mind. 



In weighing this latest integration of experience, it is to be 

 borne in mind that it stands for much more than a generaliza- 

 tion of special observations along a single line ; it is at once 

 the first and most brilliant intellectual gem of the Renaissance, 

 the unformulated complement of that quartet of principles so 

 evidently framed through its unacknowledged aid, and the most 

 comprehensive generalization of that youngest of the sciences 

 which depends on all the others for its methods and funda- 

 mental laws. Thus far the formula is new ; it has not yet been 

 tested by generations of thinkers, like the four formulas already 

 crystallized in the speech and literature of Science ; yet it is so 

 harmonious with these and so essential to their integrity as to 

 give promise of finding a place in the group. If so, it must 

 be considered to represent at the same time the earliest and the 

 latest of the cardinal principles, the first-cut block and the last- 

 set keystone in the structure of consciously organized knowl 

 edge, and the common gift of budding naturalism and maturing 

 Anthropology. 



So the cardinal principles of Science may be reckoned as
