100 NAMES AND PROPOSITIONS. 



or may be supposed to be, conveyed. Feelings are of 

 four sorts : Sensations, Thoughts, Emotions, and 

 Volitions. What are called perceptions are merely a 

 particular case of Belief, and belief is a kind of 

 thought. Actions are merely volitions followed by an 

 effect. If there be any other kind of mental state not 

 included under these subdivisions, we did not think 

 it necessary or proper in this place to discuss its 

 existence, or the rank which ought to be assigned 

 to it. 



After Feelings we proceeded to Substances. 

 These are either Bodies or Minds. Without entering 

 into the grounds of the metaphysical doubts which 

 have been raised concerning the existence of Matter 

 and Mind as objective realities, we stated as sufficient 

 for us the conclusion in which the best thinkers are 

 now very generally agreed, that all we can know of 

 Matter is the sensations which it gives us, and the 

 order of occurrence of those sensations ; and that 

 while the substance Body is the unknown cause of 

 our sensations, the substance Mind is the unknown 

 percipient. 



The only remaining class of Nameable Things is 

 Attributes ; and these are of three kinds, Quality, 

 Relation, and Quantity. Qualities, like substances, 

 are known to us no otherwise than by the sensations 

 or other states of consciousness which they excite ; 

 and while, in compliance with common usage, we have 

 continued to speak of them as a distinct class of 

 Things, we showed that in predicating them no one 

 means to predicate anything but those sensations or 

 states of consciousness, on which they may be said to 

 be grounded, and by which alone they can be defined. 

 Relations, except the simple cases .of likeness and 

 unlikeness, succession and simultaneity, are similarly
