傑克·倫敦的遺稿保管人，Irving Shepard（歐文·謝帕德）在介紹1956年出版的倫敦小說集時引用了“傑克·倫敦的信條”：
我寧願是燃燒過後的灰燼也不願為地上的灰塵！
我寧願讓點點星火猛烈燃燒殆盡也不願任其幹腐。
我寧願做壹閃而過的流星，讓每壹點碎片都擦出火光，也不願做死寂的恒星。
人的職責是生活，而不是存在。
我不會浪費時間試圖延長壽命。
但，我會用盡生命中的每壹秒。
Jack London Credo
London's literary executor, Irving Shepard, quoted a "Jack London Credo" in an introduction to a 1956 collection of London stories:
I would rather be ashes than dust!
I would rather that my spark should burn out in a brilliant blaze than it should be stifled by dry-rot.
I would rather be a superb meteor, every atom of me in magnificent glow, than a sleepy and permanent planet.
The function of man is to live, not to exist.
I shall not waste my days trying to prolong them.
I shall use my time.
