19th century philosopher Friedrich Nietzsche was a great hiker who spent much of the last decade of his life in the high country of Switzerland. John Kaag is a 21st century philosopher who travelled to the Swiss Alps with the aim of hiking the same trails as Nietzsche, and putting into practice some of Nietzsche's recommendations for "becoming who you are". In his memoir Hiking With Nietzsche, what John Kaag finds is that following in the footsteps of the great German thinker requires big shoes.
