Coarseness

Modern culture does not really promote introspection, contemplation or spiritual inquiry.
People are led by money, advertising, television, fashion technology and superficial interests.

Few people possess the patience or the interest to delve deeper.
It simply isn't fashionable.

Slowly, things coarsen.
Manners, politeness and courtesy are neglected or seen as being old-fashioned and pointless.
Good diction, eloquence and intelligence are valued less, and school exam standards are lowered to compensate.
Pursuits that require time, effort, tenacity and self-sacrifice only appeal to a shrinking number of people.
