Friedrich Nietzsche 
Human, All Too Human [PDF ebook] 
A Book for Free Spirits

German scholar and thinker Friedrich Nietzsche began his career as a linguist and philologist, but over time, his work became increasingly philosophical in its scope. He came to embrace a radical point of view that prized personal freedom and choice over virtually everything else. In Human, All Too Human, Nietzsche explores the triumphs and tragic shortfalls of human nature in an eminently readable series of aphorisms and short vignettes.
