Secular Humanism: Reason, Ethics, and the Naturalistic Life Stance
Secular humanism is a comprehensive philosophy and life stance that prioritizes human reason, logic, and secular ethics. It is grounded in philosophical naturalism—the view that only natural laws and forces operate in the universe—while explicitly rejecting religious dogma, supernaturalism, and mysticism as the foundations for morality or decision-making.
At its core, secular humanism posits that human beings are capable of living ethical and moral lives without the need for religion or a belief in a deity. It does not claim that humans are inherently good or evil, nor does it suggest that humanity is superior to nature. Instead, it emphasizes the unique responsibility humans hold and the ethical consequences of their choices. A central tenet is the belief that all ideologies, whether political or religious, must be critically examined by the individual rather than accepted on faith.
To find truth, secular humanists rely on a continually adapting search driven primarily by science and philosophy. Many derive their moral frameworks from utilitarianism (maximizing overall well-being), ethical naturalism, or evolutionary ethics, with some advocating for a formal science of morality.

The Evolution of Humanist Thought
Origins and Secularism
Modern humanism emerged from a tapestry of non-religious movements during the 18th and 19th centuries. This included the influence of the Owenites, freethinkers, positivists, and radical Unitarian congregations. The term "secularism" was coined by George Holyoake, who led the movement in Britain during the mid-19th century.

The Ethical Movement
The Ethical Culture movement played a pivotal role in shaping organized humanism. Early ethical societies adopted several core principles: the belief that morality is independent of theology, a duty toward philanthropy, the synchronization of self-reform with social reform, and a preference for republican governance over monarchical structures.
In Britain, the first such society was founded in 1886. By 1896, several London societies formed the Union of Ethical Societies. This organization evolved over decades, becoming the British Humanist Association in 1967 and eventually Humanists UK in 2017.

The Rise of Organized Secular Humanism
The movement gained formal public recognition with the 1933 Humanist Manifesto I, following academic work at the University of Chicago. While the original signers identified as "religious humanists"—viewing their stance as a dynamic force to meet modern needs without a god—the movement shifted toward a more naturalistic philosophy over time.
The American Humanist Association was incorporated in 1943, and the International Humanist and Ethical Union (now Humanists International) was founded in 1952 under the leadership of Sir Julian Huxley.

Global Frameworks and Declarations
To define the movement internationally, humanist organizations developed the Amsterdam Declaration. First passed in 1952 and revised in 2002 and 2022, the declaration simplifies the humanist stance into three primary strives: to be ethical, to be rational, and to find fulfillment in life.

Other significant documents include Humanist Manifesto II (1973), which integrated scientific, ethical, democratic, and Marxist humanism, and Humanist Manifesto III (2003).

Demographics and Census Data
Estimates suggest there are between four and five million identified humanists across 31 countries, though precise numbers are difficult to track due to varying census definitions. In many regions, humanism is categorized under "No Religion."

| Scotland | 37% | 2011 |
| Australia | ~30% | Not specified |

Legal Status and Controversies
In the United States, the legal status of secular humanism has been a point of contention. In Washington Ethical Society v. District of Columbia (1957), the court granted a tax exemption to the Society, affirming that a religion does not need to be theistic to qualify as a religious organization under the law.
Conversely, some opponents of evolution have argued that teaching the theory is equivalent to teaching the "religion" of secular humanism. However, in Peloza v. Capistrano School District (1994), the U.S. Court of Appeals rejected this claim, stating that neither evolution nor secular humanism are "religions" for the purposes of the Establishment Clause.
Frequently Asked Questions
Is secular humanism a religion?
Generally, it is a non-theistic belief system or life stance. While some legal cases (like the Washington Ethical Society case) have treated non-theistic ethical organizations as religions for tax purposes, courts have also ruled that it is not a religion in the context of the Establishment Clause.
How do secular humanists determine right from wrong?
Secular humanists derive their morality from human reason, logic, and experience. Common frameworks include utilitarianism, evolutionary ethics, and ethical naturalism, emphasizing the consequences of human decisions on others.
What is the difference between humanism and atheism?
While many humanists are atheists, atheism is specifically the lack of belief in gods. Secular humanism is a broader positive philosophy that provides a framework for ethics, truth-seeking, and living a fulfilling life.
What is the "Happy Human" symbol?
The "Happy Human" is the internationally recognized symbol of humanism. It was designed by Denis Barrington in 1965 and is used by humanist organizations worldwide to represent the movement.
What is the purpose of the Humanist Manifestos?
The manifestos serve as public declarations of the movement's values. They have evolved from the 1933 document, which sought to create a dynamic non-theistic "religion," to later versions that emphasize a naturalistic, scientific, and planetary approach to human existence.
