Power tends to corrupt and absolute power corrupts absolutely.
It is said that power corrupts, but actually it's more true that power attracts the corruptible. The sane are usually attracted by other things than power.
Because power corrupts, society's demands for moral authority and character increase as the importance of the position increases.
When power leads man toward arrogance, poetry reminds him of his limitations. When power narrows the area of man's concern, poetry reminds him of the richness and diversity of existence. When power corrupts, poetry cleanses.
Power tends to corrupt, and absolute power corrupts absolutely.
