17. Mankind in general love pleasure, particularly the 

 organic, more than they fear pain, even when pain precedes 

 the pleasure, but more especially when pleasure precedes, 

 and the consequent pain is in an}-^ degree doubtful. Nay, 

 the gratification of the passions of love and revenge and the 

 desire of fame frequently overcome the fear of certain pain, 

 whether preceding or following. 



18'. Past pleasures, if moderate, are soon forgotten, if in- 

 tense, their recollection is attended with melancholy or regret, 

 or even with sorrow, grief or remorse, but the recollection of 

 past pains or dangers, on the contrary, is pleasing, by con- 

 trast with our actual state of freedom from them. As they 

 are generally more intense than pleasures are, they are longer 

 remembered. 



JS''. The intensity of corporeal pleasures diminishes in pro- 

 portion to their duration, but the intensity of corporeal pain 

 increases with its duration. On the contrary, the intensity 

 of oriental pleasure increases with its duration, and that of 

 mental pain diminishes.
