AN EXPOSITION AND CRITICISM. 315 



visible minimum or /8 as infinitely divisible ; but it is (b) pc^itively 

 conceivable as relative, i.e., as an indefinite past, present or future, 

 and also as an indefinite mean between an absolute minimum and an 

 infinite divisibility. Secondly, Time may be considered in relation to 

 the things it contains : and these are either (a) coinclusive, when a 

 if contemporaneous, they are identical apparently and in thought, /8, 

 if of different times, they appear different, but are thought identical ; 

 •or (5) coexclusive, when they are mutually either prior, posterior, or 

 contemporaneous. The impossibility of thinking as nonexistent 

 what has once been thought as existent in time affords the mental 

 principle of causality. 



ii. Extensive quantity, Extension or Space may likewise be coxi- 

 sidiexedi firstly in itself: and as such it is (a) positively inconceivable 

 a, as infinitely unbounded or absolutely bounded, /3 as infinitely divi- 

 sible or absolutely indivisible ; but it is {b) positively conceivable 

 either as an indefinite whole or as an indefinite part. Secondly, it 

 may be considered in the things which it contains : and these may be 

 viewed (a) in relation to space, when the extension which they occupy 

 is called their place and the change of their place gives their motion, 

 or (b) in relation to each other, when, a if inclusive, they originate 

 the relation of containing and contained, /3 if coexclusive, that of 

 situation. The inability to conceive as nonexistent what has once 

 been conceived as existent in space affords the ultimate incompressi- 

 bility of matter ; and the primary qualities are all, as has been 

 shown, dependent on space. 



iii. Intensive jpia7itity. Intension or Degree, is thought as applying 

 not, like Time and Space, to substances, but to what, in the strictest 

 sense of the term, are called qualities. Firstly in itself it is («) posi- 

 tively inconceivable a absolutely, either as least or greatest, ^ infinitely, 

 as without limit either in increase or in diminution; but it is {b) posi- 

 tively conceivable as relative, as indefinitely high or higher, low or lower. 

 Secondly, the things thought under it, (a) if of the same intension, 

 are correlatively uniform, (6) if of different, are correlatively higher or 

 lower {Discussions, pp. 601-633; compare also II., pp. 366-413.)

The feelings of pleasure and pain are phenomena that accompany 

 all our conscious existence,; but since we consciously exist only 

 inasmuch as we consciously exert our various powers, it must be in
