Christianity, being the greatest moral force of the day, attracted Nietzsche's attention the most, and in "The Dawn of Day" much space is devoted to a consideration of it. While in tone these paragraphs are milder than those which followed in "The Antichrist," they nevertheless are among the profoundest criticisms which Nietzsche made of Nazarene morality. Though only a portion of the aphorisms contained in this work are devoted to an evaluation of theological modes of conduct, stumbling blocks are thrown in the path of an acceptance of Jewish ethics which the most sapient of modern ecclesiastics have been unable to remove. Out of certain aphorisms found here grew "The Antichrist" which is the most terrible and effective excoriation that Christianity has ever called forth. Beginning on page 66 of "The Dawn of Day" there appears one of Nietzsche's most fundamental passages dealing with Christianity. It is called "The First Christian," and is an analysis of the Apostle Paul. No theological dialectician has been able to answer it. Here is an aphorism so illuminating, so profound, yet so brief, as to dazzle completely the lay mind. However, Christianity is but one of the subjects dealt with in "The Dawn of Day." The book covers the whole field of modern morality. Says Nietzsche in his introduction; "In this book we find a 'subterrestrial' at work, digging, mining, undermining.... I went down into the deepest depths; I tunnelled to the very bottom; I started to investigate and unearth an old _faith_ which for thousands of years we philosophers used to build on as the safest of all foundations.... I began to undermine our _faith in morals."_ It is true that from the beginning of history there has existed a ruling scale of values determining the acts of humanity. Morality implies the domination of certain classes which, in order to inspire reverence in arbitrary dictates, have invested their codes with an authority other than a human one. Thus has criticism been stifled. Morality has had the means of intimidation on its side, and has discouraged investigation by exercising severe penalties. Consequently morality has accumulated and grown, gathered power and swept on without its thinkers, its philosophers or its analysts. Of all the sciences, the science of conduct has been the last to attract investigators.
