“Examine the lives of the best and more fruitful men and peoples, and ask yourselves whether a tree, if it is to grow proudly into the sky, can do without bad weather and storms: whether unkindness and opposition from without, whether some sort of hatred, envy, obstinacy, mistrust, severity, greed and violence do not belong to the favouring circumstances without which a great increase even in virtue is hardly possible. The poison which destroys the weaker nature strengthens the stronger – and he does not call it poison, either.”

German philosopher and writer

Friedrich Nietzsche was a German philosopher and writer. He began as a classical philologist, then turned to philosophy early in his academic career, and is known for a body of work that drew wide scholarly attention and lasting popular interest. In 1869 he became Professor of Classical Philology at the University of Basel, but he resigned in 1879 because of long-standing health problems. After that he lived as an independent writer, often in solitude and financial insecurity, moving between Switzerland, Italy, and southern France. He completed much of his main work in the following decade, before a neurological collapse in 1889 ended his working life.
