4 r8 THE SCIENCE OF LOGIC 



problem of classification. What is &quot; Aggregation &quot; ? On what will the 

 formation of intermediate classes depend ? Can logic suggest the proper 

 attributes to select as grounds of classification ? On what will the selection 

 depend ? Distinguish between two kinds of aim or purpose in classification, 

 and two resulting kinds of classification. Discuss the designations &quot; natural &quot; 

 and &quot;artificial&quot;. Illustrate classification for &quot;special purposes&quot;. Is 

 classification the arrangement of objects f What is Diagnosis ? To what 

 end is artificial classification usually a means ? How do the intermediate 

 classes of an artificial classification compare with those of a natural classifica 

 tion of the same objects ? What is the aim of classification for general 

 purposes ? What test or tests have been suggested for determining which 

 attributes are &quot; most important,&quot; as grounds of division, in a natural classi 

 fication ? Do we discover &quot; resemblances &quot; between members of a class 

 after we have arrived at that class on the basis of a previously known &quot; im 

 portant attribute &quot; ? or do we, vice versa, discover the &quot; importance &quot; of the 

 attribute after we have arrived at the class on the basis of &quot; resemblances &quot; ? 

 Can the &quot; importance &quot; of an attribute be determined by the number of 

 others involved in it ? Is &quot; degree of resemblance &quot; a sound basis for the 

 aggregation of individuals into groups, and of these into wider groups ? Is it 

 wrong to &quot;judge by appearances&quot;? Why is classification on general re 

 semblances called &quot;Natural&quot;? Compare the difference between natural, 

 with that between artificial, classes. What sense do botanists and biologists 

 attach to the terms &quot;species&quot; and &quot;genus&quot;? What do they regard as the 

 origin, and what as the test, of a species ? How has advance in knowledge 

 modified their views ? Do &quot; natural &quot; groups in the organic world sometimes 

 fade away into one another? In doubt about the relative importance of 

 points of resemblance, what will influence our decision ? How has the 

 evolution hypothesis affected the interpretation of &quot; affinity &quot; and &quot; species,&quot; 

 and the selection of &quot; important &quot; attributes ? Define scientific nomenclature. 

 Describe two systems. Why are the names of botanic species and varieties 

 not definitions ? What is scientific terminology ? Enumerate the character 

 istics of a good terminology. 



CHAP. V. What are axioms or principles ? What bearing have their 

 predicates on all our knowledge ? Is the classification of all possible predi 

 cates a logical or a metaphysical problem ? What is the nature of Aristotle s 

 classification of the &quot; Categories &quot; ? Define &quot; Category,&quot; &quot; Praedicamentum &quot;. 

 Compare the praedicamenta with the praedicabilia. Are the former a classi 

 fication of relations ? Distinguish between substantia prima and substantia 

 secunda ; between the latter and accidens or attribute. How would you 

 reason out the tenfold scheme of Aristotle ? Enumerate the categories, giving 

 subdivisions of each. Discuss the different interpretations of the doubtful 

 categories. Distinguish between Quantitas, Ubi, and Quando ; between Ubi 

 and Situs. To which category does &quot; habit &quot; belong ? Are the categories 

 based on the parts of speech ? Refer to their appropriate categories the sub 

 stantive, the adjective, the verb. Connect the pronoun, the adverb, the 

 preposition, the conjunction, with the categories. Show, by an example, how 

 the categories exhaust all the possible heads of inquiry about an individual. 

 Find a place for mental states in the categories. Do language-roots indicate 

 individual subjects, or abstract predicates ? Are the. categories classes of
