Arthur Schopenhauer ( ; ] ; 22 February 1788 – 21 September 1860) was a German philosopher.
 He is best known for his 1818 work "The World as Will and Representation" (expanded in 1844), wherein he characterizes the phenomenal world as the product of a blind and insatiable metaphysical will.
 Proceeding from the transcendental idealism of Immanuel Kant, Schopenhauer developed an atheistic metaphysical and ethical system that has been described as an exemplary manifestation of philosophical pessimism, rejecting the contemporaneous post-Kantian philosophies of German idealism.
 Schopenhauer was among the first thinkers in Western philosophy to share and affirm significant tenets of Eastern philosophy (e.g., asceticism, the world-as-appearance), having initially arrived at similar conclusions as the result of his own philosophical work.
On the Basis of Morality (German: "Ueber die Grundlage der Moral" , 1840) is one of Arthur Schopenhauer's major works in ethics, in which he argues that morality stems from compassion.
 Schopenhauer begins with a criticism of Kant's "Groundwork of the Metaphysic of Morals", which Schopenhauer considered to be the clearest explanation of Kantian ethics.
Charles Edward Rice (August 7, 1931 – February 25, 2015) was an American legal scholar, Catholic apologist, and author of several books.
 He is best known for his career at the Notre Dame Law School at Notre Dame, Indiana.
 He began teaching there in 1969, and in 2000 earned professor emeritus status.
 He continued to teach an elective course called "Morality and the Law" each year in retirement.
Jeff Schweitzer (born 1957) is an American non-fiction author, scientist, political commentator and proponent of scientific skepticism.

Yamanoue no Okura (山上憶良 , also written as 山於億良, 660?
–733?)
 was a Japanese poet, the best known for his poems of children and commoners.
 He was a member of Japanese missions to Tang China.
 He was also a contributor to the Man'yōshū and his writing had a strong Chinese influence.
 Unlike other Japanese poetry of the time, his work emphasizes a morality based on the teachings of Confucius.
 Most scholars believe that he was born in 660, on the basis of his Chinese prose "Chin'a Jiai-bun" recorded in the fifth volume of Man'yōshū as a work written in 733 (Tenpyō 5), in which he says, "In this year, I am 74."

"The Five Thousand Year Leap: Twenty-Eight Great Ideas That Are Changing the World" is a book that was published in 1981 by author W. Cleon Skousen.
