Love is blind; friendship closes its eyes. - Friedrich Nietzsche

"The most perfidious way of harming a cause consists of defending it deliberately with faulty arguments."

"Art is the proper task of life."

"Convictions are more dangerous foes of truth than lies."

"The man of knowledge must be able not only to love his enemies but also to hate his friends."

"Hope in reality is the worst of all evils because it prolongs the torments of man."
