Arthur Schopenhauer 
Essays of Arthur Schopenhauer; On Human Nature 

Excerpt: "The following essays are drawn from the chapters entitled Zur Ethik and Zur Rechtslehre und Politik which are to be found both in Schopenhauer’s Parerga and in his posthumous writings. As in my previous volumes, so also in this, I have omitted a few passages which appeared to me to be either antiquated or no longer of any general interest. For convenience’ sake I have divided the original chapters into sections, which I have had to name; and I have also had to invent a title which should express their real scope. The reader will find that it is not so much Ethics and Politics that are here treated, as human nature itself in various aspects.’"
