CHAPTER II. 



TEEMS. 



EVERY proposition expresses the resemblance or differ-

 concrete and palpable things are the objects of thought. 

 The youngest child knows the difference between a hot and 

 a cold body. The dog can recognise his master among a 

 hundred other persons, and animals of much lower intel- 

 ligence know and discriminate their haunts. In all such 

 acts there is judgment concerning the likeness of physical 

 objects, but there is little or no power of analysing each 

 object and regarding it as a group of qualities.

 in colour may differ in odour. The mind learns to regard
