OF THE INTELLIGENCE AND OF INSTINCT. 161 



power varies almost in every person. It may be destroyed 

 by disease or strengthened (?) by exercise : active in youth, it 

 becomes dull with age, especially as regards the events of 

 yesterday, whilst the sensations of youth are readily recalled, 

 even in extreme old age. Youth, then, is the age for acquiring 

 knowledge. 



Nothing is more capricious than this faculty called memory; 

 it would seem as if there were so many distinct memories, 

 which different men possess in various degrees. Some have 

 a memory for words, others for dates, others for language, in 

 its largest sense ; and by disease one of these memories may 

 be destroyed and not the others. But there exist no good 

 grounds for supposing that there really exist more memories 

 than one. 



311. By the faculty of * judgment we compare the sensa- 

 tions derived from all sources with each other, study their 

 relations and draw from them certain conclusions or opinions.; 

 and it is this faculty which especially characterizes man from 

 all that lives. By reflection he studies his own faculties, 

 and, when it is sound, measures them accurately with others. 



312. The imagination is a faculty which plays an im- 

 portant part in the phenomena of the human intelligence ; it 

 is connected with the power we have of creating signs to 

 represent our ideas. 



313. Finally, the will, without which our other faculties 

 were given to no purpose ; the will, by which we seek plea- 

 sure and safety, and avoid pain and danger. With this, 

 however, there is joined a tendency to induction, and, super- 

 added as it were, the sentiment of justice, of the beautiful, 

 of pity ; in a word, all the moral sentiments so peculiarly 

 human, and which, though general, men possess in such varied 

 degrees. 



314. These faculties have strong affinities with others, 

 which may be named affective, such as parental and filial 

 affection for our fellow-creatures, &c.; and these, on the other 

 hand, have strong affinities with our natural instincts. In 

 man, these instincts are but little developed, compared with 

 what we find in other animals, in whom they play a most 

 important part. 



315. Principles of Actions. The various faculties we 

 have just enumerated are the determining cause of most of 

 our actions.
