Question: Who was an early ethical egoist alternative to the philosophy also known as Ruism?
Context: Yang Zhu (; 440–360 BC), also known as Yang Zi or Yangzi (Master Yang), was a Chinese philosopher during the Warring States period.  An early ethical egoist alternative to Mohist and Confucian thought, Yang Zhu's surviving ideas appear primarily in the Chinese texts "Huainanzi", "Lüshi Chunqiu", "Mengzi", and possibly the "Liezi" and "Zhuangzi". The teletransportation paradox or teletransport paradox (also known in alternative forms as the duplicates paradox) is a thought experiment on the philosophy of identity that challenges some of our common intuitions on the nature of self and consciousness.  It first appeared in full published form presumably in Derek Parfit's 1984 book "Reasons and Persons", but similar questions have been raised as early as 1775. The Code of Practices for Television Broadcasters, also known as the Television Code, was a set of ethical standards adopted by the National Association of Broadcasters (NAB) for television.  The code was established on December 6, 1951.  Compliance with the code was indicated by the "Seal of Good Practice", displayed during closing credits on most United States television programs, and on some US TV station sign-on and sign-offs from 1952 through the early 1980s. Yitzchak Blazer (1837 – 1907), also known as Reb Itzelle Peterburger, was one of the early important leaders of the Musar movement, a Jewish ethical movement based in Lithuania within the Russian Empire.  He was a student of the founder of the movement, Yisrael Salanter, and was responsible for publishing many of Salanter's letters in "Or Yisrael" ("The Light of Israel").  Blazer became the chief rabbi of St. Petersburg in 1861–62, when he was only 25 years old.  From 1880 to approximately 1891, he served as the head of the Kovno Kollel in Kaunas, Lithuania, which was founded by Salanter.  Under Blazer's direction, the kollel came to be "considered by its contemporaries as a bastion of the Mussar movement," and was attacked by the Musar movement's opponents.  He later joined Nosson Tzvi Finkel in leading the Slabodka Yeshiva, and eventually moved to Palestine where he died in 1907. Learning environment is an educational approach, cultural context, or physical setting in which education occurs.  The term is commonly used as a more definitive alternative to "classroom", but it typically refers to the context of educational philosophy or knowledge experienced by the student and may also encompass a variety of learning cultures—its presiding ethos and characteristics, how individuals interact, governing structures, and philosophy.  In a societal sense, learning environment may refer to the culture of the population it serves and of their location.  Learning environments are highly diverse in use, learning styles, organization, and educational institution.  The culture and context of a place or organization includes such factors as a way of thinking, behaving, or working, also known as organizational culture.  For a learning environment such as an educational institution, it also includes such factors as operational characteristics of the instructors, instructional group, or institution; the learning styles and pedagogies used; and the societal culture of where the learning is occurring. An ethical bank, also known as a social, alternative, civic, or sustainable bank, is a bank concerned with the social and environmental impacts of its investments and loans.  The ethical banking movement includes: ethical investment, impact investment, socially responsible investment, corporate social responsibility, and is also related to such movements as the fair trade movement, ethical consumerism, and social enterprise. Mohist consequentialism, also known as state consequentialism, is a consequentialist ethical theory which evaluates the moral worth of an action based on how it contributes to the basic goods of a state, through social order, material wealth, and population growth.  According to the "Stanford Encyclopedia of Philosophy", Mohist consequentialism, dating back to the 5th century BC, is the "world's earliest form of consequentialism, a remarkably sophisticated version based on a plurality of intrinsic goods taken as constitutive of human welfare."  The term state consequentialism has also been applied to the political philosophy of the Confucian philosopher Xunzi. Reform Judaism (also known as Liberal Judaism or Progressive Judaism) is a major Jewish denomination that emphasizes the evolving nature of the faith, the superiority of its ethical aspects to the ceremonial ones, and a belief in a continuous revelation not centered on the theophany at Mount Sinai.  A liberal strand of Judaism, it is characterized by a lesser stress on ritual and personal observance, regarding Jewish Law as non-binding and the individual Jew as autonomous, and openness to external influences and progressive values.  The origins of Reform Judaism lay in 19th-century Germany, where its early principles were formulated by Rabbi Abraham Geiger and his associates; since the 1970s, the movement adopted a policy of inclusiveness and acceptance, inviting as many as possible to partake in its communities, rather than strict theoretical clarity.  Its greatest center today is in North America. Confucianism, also known as Ruism, is described as tradition, a philosophy, a religion, a humanistic or rationalistic religion, a way of governing, or simply a way of life.  Confucianism developed from what was later called the Hundred Schools of Thought from the teachings of the Chinese philosopher Confucius (551–479 BCE), who considered himself a retransmitter of the values of the Zhou dynasty golden age of several centuries before.  In the Han dynasty (206 BCE – 220 CE), Confucian approaches edged out the "proto-Taoist" Huang-Lao, as the official ideology while the emperors mixed both with the realist techniques of Legalism.  The disintegration of the Han political order in the second century CE opened the way for the doctrines of Buddhism and Neo-Taoism, which offered spiritual explanations lacking in Confucianism. The philosophy of Max Stirner (25 October 1806 - 26 June 1856), a German philosopher, is credited as a major influence in the development of nihilism, existentialism, post-modernism, and anarchism (especially of egoist anarchism, individualist anarchism, postanarchism, and post-left anarchy).  Max Stirner's main philosophical work was "The Ego and Its Own", also known as "The Ego and His Own" ("Der Einzige und sein Eigentum" in German, which means, more accurately in German, "The Individual and his Property").
