ing his philosophical tenets, turns upon the value 

 and the origin of verbal propositions, that this 

 summary sketch of the relations of language to the 

 thinking process will probably not be deemed 

 superfluous. 



So large an extent of the field of thought is 

 traversed by Hume, in his discussion of the verbal 

 propositions in which mankind enshrine their be- 

 liefs, that it would be impossible to follow him

 than any other part of his teaching, contributed to 

 give him a prominent place in the history of 

 philosophy.

 naturally be divided into two kinds, to wit, relations of 

 ideas and matters of fact. Of the first kind are the sciences 

 of geometry, algebra, and arithmetic, and, in short, every 

 affirmation which is either intuitively or demonstratively 

 certain. "That the square of the hypothenuse is equal to 

 the square of the two sides, is a proposition which expresses 

 a relation between these two figures. That three times five 

 is equal to the half of thirty, expresses a relation between 

 these numbers. Propositions of this kind are discoverable
