" Ages are spent in collecting materials, ages more in separating and combining 



them. Even when a system has been formed, there is still something to add, to alter, 



or to reject. Every generation enjoys the use of a vast hoard bequeathed to it by 



antiquity, and transmits that hoard, augmented by fresh acquisitions, to future ages. 



In these pursuits, therefore, the first speculators lie under great disadvantages, and, 



even when they fail, are entitled to praise."
