It was in this respect that they were warmly recommended to me some years ago by my excellent friend, Professor Harnack, the historian of Dogma, a writer with a fine and prudent enthusiasm for all ennobling literature. It is to him that I owe the resolve to perform for the maxims, as far as I could, the office of translator; a humble office, but not, as I have good reason to know, without its difficulty, or, as I venture to hope, without its use. Of many of them the language is hardly lucid even to a German, and I have gratefully to acknowledge the assistance I have received from the privilege of discussing them with so distinguished a man of letters. To Professor Huxley I am also deeply indebted. I owe him much for friendly encouragement, and still more for help of an altogether invaluable kind; for in its measure of knowledge and skill, it is admittedly beyond the power of any other living Englishman. The maxims deal, not alone with Life and Character, where most of them are admirable, but also with certain aspects of Science and Art; and these are matters in which I could exercise no judgment myself, although I understood that, while many of the maxims on Science and Art were attractive, they were not all of great merit. Professor Huxley not only did me the honour to select the maxims on Science, but he was further good enough to assist me with them, and to read and approve the translation as it now stands. The weight and the interest of his authority will thus give additional value to that section of the book, and also do much to overcome the objections that exist to making a selection at all.
