knowledge, ranks as an accident, but an inseparable accident, 

 of the species crow. 



Separable Accidents are tbose which are found, in point of 

 fact, to be sometimes absent from the species ; which are not 

 only not necessary, but not even universal. They are such as 

 do not belong to every individual of the species, but only to 

 some individuals; or if to all, not at all times. Thus the 

 colour of an European is one of the separable accidents of 

 the species man, because it is not an attribute of all human 

 creatures. Being born, is also (speaking in the logical sense) 

 a separable accident of the species man, because, though an 

 attribute of all human beings, it is so only at one particular 

 time. A fortiori those attributes which are not constant even 

 in the same individual, as, to be in one or in another place, to 

 be hot or cold, sitting or walking, must be ranked as separable 

 accidents.
