"Another reason why so many kinds of creatures were made, might 

 be to exercise the contemplative faculty of man ; which is in nothing so 

 much pleased, as in variety of objects. We soon grow weary of one 

 study ; and if all the objects of the world could be comprehended by us, 

 we should, with Alexander, think the world too little for us, and grow 

 weary of running in a round of seeing the same things. New objects 

 afford us great delight, especially if found out by our own industry." 



John Ray, The Wisdom of God in Creation.
