100 Humanist Events That Changed the World

FI Editors' Picks The Last 1,000 Years

The following article is from Free Inquiry magazine, Volume 20, Number 2.

Humanistic ideals can be traced back to the dawn of civilization, but they have flourished more in the past 1,000 years than ever before. When the rights of human beings gain respect, when democracy is nourished, when science and reason expand human knowledge, when secular ideas arise and influence the world, humanism blossoms. The following is a catalogue of events that have signaled dramatic growth in the influence of these humanist ideals in the last millennium. The list, which is neither exhaustive nor exacting, has been selected by Free Inquiry editors. It reminds us that, if the past prepares the future and there is thus a further flowering of humanism, the next thousand years may be more promising than many humans believe. 


  • Scholastic Awakening (1050-1200). Revived tradition of analytical inquiry; sparked foundation of Europe's first universities.
  • First recorded use of a compass for navigation, in China (1117). Navigational tool not dependent on star observations expands range, reliability of sea travel.
  • Marco Polo travels to China (1298). Creates new Western awareness of lands and peoples to the east.
  • Johann Gutenberg invents movable-type printing press (1450). The Bible is first book to be mass-produced.
  • Publication of Copernicus's "On the Revolutions of the Heavenly Spheres" (1543). Positing the sun, not the Earth, as the center of the universe, Copernicus discredited scripture as a guide to the cosmos and paved the way for all future developments in astronomy; vindicated empirical inquiry over Aristotelian authority as a means of determining truth.
  • The Scientific Revolution (1600-1700). Galileo, Newton, Kepler demonstrated the power of empirical inquiry to explain phenomena; undercut scripture-based views of the universe and humanity's place therein.
  • The birth of economics (1770s). Based on post-mercantilist view of what constitutes wealth, work of Adam Smith and others reduces effective powers of royalty while encouraging industrial, commercial growth.
  • Publishing of Edward Gibbon's "Decline and Fall" (1776-1788). Implicated Christianity and its hostility toward intellectual inquiry in the fall of Rome; popularized idea that religion could be responsible for sweeping, negative social consequences.
  • Malthus introduces modern notion of overpopulation (1798). First to suggest that overpopulation posed a genuine threat; pioneer in advocating for deliberate management of human population's size.
  • Rosetta Stone found (1799). Enabled translation of Egyptian hieroglyphs; later scholars would demonstrate that many Christian beliefs and practices have Egyptian roots.
  • Publication of Darwin's "Origin of Species" (1859). Its naturalistic account of the origin of life made a fully nontheistic worldview credible to millions.
  • Quantum Theory developed (1900-1930). Established modern understanding of the subatomic universe; freed scientific naturalism from dependence on strict determinism.
  • Publication of Einstein's theories of "Special and General Relativity" (1905, 1916). Revolutionized physics; stunning confirmations of certain Einsteinian predictions smoothed the way for public comprehension of the new physics.
  • Invention of the computer (ENIAC, 1946). Electronic computing would usher in the so-called Third Industrial Revolution while flattening social and commercial institutions and democratizing access to information.
  • Discovery of DNA (1953). Paving the way for unlocking the genetic code, "double helix" discovery also closed off one of the mysteries believers commonly assigned to exclusive control of the deity.
  • Amino acids produced in test tube (1953). Demonstrated partial pathway by which life might arise from nonlife without divine intervention; enhanced plausibility of strict naturalism among popular audiences.
  • Space Exploration begun (1957). Ushered in unprecedented era of growth in scientific knowledge and (for a time) public appreciation of science.
  • Advent of genetic engineering (1973). For first time, humans can influence-as well as be influenced by-their genetic endowments.
  • First test-tube baby born in England (1978). Extends human control over our own biology; confirms the new, mutual independence of sex and reproduction.


  • First commission of a work of art by a secular patron (1434). Ended Roman Catholic Church's monopoly over creation of artworks in the West.
  • The Renaissance (1450-1550). In art, music, architecture, and politics, established humanity rather than God, this world rather than the next, as the focus of human endeavor.
  • Work of Shakespeare and Christopher Marlowe (late 1500s). With their vivid characterizations, these great plays popularized the idea of individual personalities, not fate or the gods, as primary shapers of events.
  • Poet Percy Bysshe Shelley attacked for his atheism (1811). Though expelled from Oxford for co-publishing The Necessity of Atheism, Shelley became West's first open atheist to enjoy successful literary career.
  • Poet Edward FitzGerald's discovery and translation of Omar Khayyam's Rubaiyat (1859). Popularized a life-affirming, this-worldly viewpoint rooted in a non-Christian culture.
  • Harlem Renaissance (1920s). First distinctly African American voices in music and literature to win prestige, recognition among mainstream critics.


  • Averroes (1126-1198) applies skepticism to study of Islam. Demonstrated applicability of rational inquiry to the study of all subjects, including religion.
  • Publication of Maimonides' "Guide to the Perplexed" (1176). First great secularizing, demythologizing work in the Jewish tradition.
  • "In Praise of Folly" by Erasmus published (1509 English edition 1549). Pioneering critique of theology and clericalism.
  • Machiavelli's "The Prince" (1513). Though ruthless, this guide for rulers was the first to portray government as a secular exercise best judged by its results, not by the dictates of religious law.
  • Work of Montaigne (mid-1500s). His essays encompassed every aspect of life and established autobiography as a humanistic literary form.
  • Publication of Hobbes's "Leviathan" (1651). Its notion of the social contract rooted the ruler's power not in divine sanction, but in the consent of the governed.
    Literary and philosophical contributions of Voltaire (1694-1798). Pre-eminent essayist, dramatist and philosophe, his writings and his life exemplified the inquiring, iconoclastic Enlightenment sensibility. Popularized profound arguments against the tenets of Christianity.
  • Activity of French philosophes (mid 1700s). Montesquieu, Voltaire, Diderot, Rousseau, d'Alembert, d'Holbach, Condorcet, and others popularized Enlightenment ideals of reason, empiricism, and humanism in the arts, sciences, and politics.
  • Locke's "Letter on Toleration" (1689). Pioneering statement that religious belief is a matter of individual conscience (though Locke rejected toleration for atheists).
  • Writing of Hume's "Dialogues Concerning Natural Religion" (1779). This posthumous work leveled a withering attack, still powerful today, against belief in miracles and religious supernaturalism generally.
  • Publication of Mary Wollstonecraft's "Vindication of the Rights of Women" (1792). Pioneering women's rights treatise introduced key feminist concepts, inspired many 19th-century suffragists.
  • Publication of Thomas Paine's "The Age of Reason" (1794). This deistic critique of Christian doctrine has probably guided more inquirers out of their faith than any book save the Bible.
  • Defense of utilitarianism by Jeremy Bentham (late 1700s) and J.S. Mill (mid-1800s). Popularized idea that moral precepts should be judged by their consequences rather than by their conformity to pre-existing, often religious, norms.
  • Schopenhauer's denunciations of religion (1818-1851). Popularized a wholly this-worldly view that acknowledged the importance of will and emotion as well as reason.
  • Ludwig Feuerbach publishes the "Essence of Christianity" (1841). This influential work portrayed Christianity as inhumane and pioneered accounting for its origins and persistence on psychological grounds.
  • J.S. Mill's "On Liberty" (1859). Unequalled defense of liberal politics premised on the value of personal autonomy, choice, and individuality.
  • Marx's "Das Kapital" (1867-1894). Proposed a wholly secular model of history, economics, and religion, a rallying point for both reformers and dictators whose influence on the twentieth century (for good and ill) would be immense.
  • Birth of biblical "higher criticism" (early 1800s). Demonstrated that scripture could be subjected to historical analysis like other ancient texts-and convinced many literate Europeans that most religious claims are untrue.
  • Nietzsche's "Thus Spoke Zarathustra" (1883). Popularized idea of the death of God; compelling statement of nineteenth-century Western mind contemplating the new vistas revealed by discovering the bankruptcy of religion.
  • Elizabeth Cady Stanton published "Woman's Bible," vol. I (1895). First influential work to recognize the damage done by traditional Christianity to women's rights, autonomy, self-image.
  • Freud's speculations about the psychology of religious belief (1920s). Though largely discredited today, they made popular the idea of seeking this-worldly explanations for religious phenomena.
  • Dewey's "Experience and Nature" (1925) and "Reconstruction in Philosophy" (1948). Set forth an influential naturalistic conception of science, art, and values.
  • Publication of Bertrand Russell's "Why I Am Not a Christian" (1927). Next to the Bible and Paine's Age of Reason, perhaps the most effective text for encouraging Christians to outgrow their faith.
  • Development of logical positivism (1930s). Favored empirical science over metaphysics; popularized idea that religious statements are inherently meaningless.
    Publication of Simone de Beauvoir's "The Second Sex" (1949). Launched second-wave feminism, inspiring Millett, Friedan, Steinem, and others.
  • Creation of aesthetic existentialism by Jean-Paul Sartre and his circle (1950s). Popularized idea that instead of depending on religious or social institutions, people are responsible for their own lives.


  • The Crusades (1096-1251). Christendom's failure to dislodge Muslims from the Holy Land engendered popular skepticism about God's will and church authority.
