The School of Life offers radical ways to help us raid the treasure trove of human knowledge'' Independent on Sunday

Friedrich Nietzsche was a German philosopher, poet and cultural critic. He is best known for his controversial idea of ''life affirmation'' that challenged traditional morality and all doctrines. Born in 1844 outside Leipzig, Germany, his teachings inspired people in all walks of life, from dancers and poets to psychologists and social revolutionaries. Here you will find insights from his greatest works.

The Life Lessons series from The School of Life takes a great thinker and highlights those ideas most relevant to ordinary, everyday dilemmas. These books emphasize ways in which wise voices from the past have urgently important and inspiring things to tell us.
