LIB. II. 32,33. Ml 



pus sive concretum tale, in quo natura inquisita per- 

 petuo sequatur tanquam comes quidam individuus : 

 aut contra, in quo natura inquisita perpetuo fugiat, 

 atque ex comitatu excludatur, ut hostis et inimicus. 

 Nam ex liujusmodi instantiis fonnantur propositiones 

 certae et universal es; aut affirmative, aut negatives: 

 in quibus subjectum erit tale corpus in concrete, prse- 

 dicatum vero natura ipsa inquisita 89 . Etenim propo 

 sitiones particulares omnino fixce non sunt, ubi scilicet 

 natura inquisita reperitur in aliquo concreto fluxa et 

 mobilis ; viz. accedens, sive acquisita ; aut rursus rece- 

 dens, sive deposita. Quocirca particulares propositio 

 nes non habent pr&rogativam aliquam majorem, nisi 

 tantum in casu migrationis ; de quo antea dictum est. 

 Et nihilominus, etiam particulares illae propositiones 

 comparative et collatae cum universalibus multum ju- 

 vant ; ut suo loco dicetur. Neque tamen, etiam in 

 universalibus istis propositioriibus exactam aut abso- 

 lutam affirmationem vel abnegationem requirimus. 

 Sufficit enim ad id quod agitur, etiamsi exceptionem 

 nonnullam singularem aut raram patiantur. 



Usus autem instantiarum comitatus est ad angus tan- 

 dam affirmativam forinae. Quemadmodum enim in 

 instantiis migrantibus angustatur affirmatwa formae ; 

 viz. ut necessario poni debeat forma rei esse aliquid, 

 quod per actum ilium migrationis inditur aut destru-

 Instance&quot; is like the first, in having are only, in reality, more general 

 an Affirmative and a Negative side, statements embracing that which is 

 Bacon sets this Class over against common to many particulars. For 

 that of &quot; Migrating Instances.&quot; they are (according to Bacon him-

 Bacon clings to the Logical Lan- Contradictoria,&quot; and so are to be 

 guage of the Schools, against which regarded as &quot;general&quot; in the popular
