Chapter XII 



VOCATION VERSUS AVOCATION 



"Human happiness . . . seems to consist of three in- 

 gredients, action, pleasure, and indolence. And though 

 these ingredients ought to be mixed in different proportions 

 according to the different dispositions of the persons, yet no 

 one ingredient can be entirely wanting without destroying 

 in some measure the relish of the whole composition." 



David Hume.
