Impermanent?

"Where Nature is ever hidden, and cowers under mist and cloud, snow and darkness, there man feels himself master; he regards his desires, his works, as permanent; he wants to perpetuate them, he looks towards posterity, he raises monuments, he writes biographies; he even goes the length of erecting tombstones over the dead. So busy is he that he has not time to consider how many monuments crumble, how often names are forgotten!” 

― Rabindranath Tagore
