 a mistake in the domain of research to lay undue stress upon any 

 one class of considerations, or upon an analysis of society from

 demands by a single agency. There are two thoughts to which 

 this analysis seems to me to lead. The first is that social sciences 

 cannot with safety be severed from their practical application; and 

 the second is that, as liberty of action is found in the balance of 

 power, so liberty of thought (I mean liberty, not license) is attained 

 when each investigator in any of the sciences of pertain to human 

 relations recognizes that what he says is true only as it bears har- 

 monious relations to that which other investigators may say.
