COEXISTENCES INDEPENDENT OF CAUSATION. 123 



to itself. In organized beings, indeed, there are abundance of 

 propositions ascertained to be universally true of superior 

 genera, to many of which the discovery hereafter of any excep- 

 tions must be regarded as extremely improbable. But these, 

 as already observed, are, we have every reason to believe, pro- 

 perties dependent on causation. 



Uniformities of coexistence, then, not only when they are 

 consequences of laws of succession, but also when they are 

 ultimate truths, must be ranked, for the purpose of logic, 

 among empirical laws ; and are amenable in every respect to 

 the same rules with those unresolved uniformities which are 

 known to be dependent on causation.
