Overview
De Vrije Gedachte, formally known as Vrijdenkersvereniging De Vrije Gedachte, is a Dutch association rooted in the nineteenth-century freethought movement. It advocates intellectual independence and the use of reason, logic and the natural sciences in opposition to religious dogma, clerical authority, supernatural claims and what it regards as inherited prejudice. Although the organization has often been associated with atheism, its broader historical identity is that of a freethinkers' movement: it has brought together people who reject compulsory belief and defend the freedom to examine moral, political and philosophical questions without deference to religious institutions. The association was founded in Amsterdam in 1856 under the name De Dageraad, meaning “The Dawn.” Its origins lay in a network of radical publishers, intellectuals and freemasons connected with the magazine De Dageraad, which began publication in 1855. The movement developed in a Netherlands where Christianity held a dominant position in public life, education and politics. Early members used natural philosophy, science and materialist or deist arguments to challenge revealed religion and the idea that churches possessed an exclusive authority over truth and morality. A related Rotterdam society, De Lichtstraal, joined De Dageraad in 1857, helping establish a national organization. During the late nineteenth century, De Dageraad experienced both growth and internal conflict. Some members departed to form the socially oriented association De Humaniteit, while the organization briefly used the name Het Vrije Onderzoek between 1873 and 1876. The two groups later reconciled, and De Humaniteit merged into De Dageraad in 1878. The association subsequently strengthened its organizational structure, expanded its publicity work and adopted an increasingly explicit materialist and atheist orientation. Its intellectual environment was influenced by Charles Darwin, Ernst Haeckel, Ludwig Büchner, Jacob Moleschott and Baruch Spinoza. Freethinking also became closely connected with women's emancipation, with figures including Aletta Jacobs, Wilhelmina Drucker, Elise Haighton and Titia van der Tuuk contributing to the movement's public and organizational life. Membership and influence expanded substantially in the early twentieth century. The association grew from several hundred members in the early 1900s to thousands by the interwar period and maintained a network of regional branches. It promoted separation of church and state, secular public education and public alternatives to church-controlled poor relief. Some members attempted to establish an independent electoral movement, but the Freethinkers into Parliament association achieved only limited electoral support and soon disappeared. De Dageraad itself avoided formally binding the whole association to a political party because its membership included a wide range of political views. Broadcasting became one of the association's most significant public activities. In 1928, members established the Vrijdenkers Radio Omroepvereeniging, or VRO. Its broadcasts addressed religion, politics, fascism and freedom of thought. The service encountered censorship and political pressure, particularly after a broadcast concerning Benito Mussolini and the suppression of thought. Although the VRO eventually received regular airtime, its programs were subject to restrictions and were eventually withdrawn in 1936. The association and its publications were also targeted by religious organizations, authoritarian movements and government measures, including restrictions connected with anti-blasphemy legislation and limits on civil servants' involvement. The German occupation of the Netherlands in 1940 forced De Dageraad to dissolve its local branches, destroy or hide records and discontinue its publication. Several associated intellectuals suffered persecution; Jewish atheist members Louis Fles and Leo Polak died during the occupation and imprisonment, while Anton Constandse survived detention. After the Second World War, the organization was re-established and recovered its publications, branches and membership. It cooperated, though not without tensions, with the Humanistisch Verbond and Humanitas. In 1957, it adopted the name De Vrije Gedachte, translated as “The Free Thought,” and its magazine became Bevrijdend denken, or “Liberating Thinking.” The association's continuing identity rests on secularism, atheism or nonbelief, criticism of religious privilege, freedom of expression and the promotion of autonomous judgment. It is distinct from a commercial consumer brand: its name represents an ideological and civic organization whose public role has historically been expressed through periodicals, meetings, radio, educational activity and campaigns concerning church–state separation and freedom from religious authority.
History
The history of De Vrije Gedachte begins with the organized Dutch freethought movement of the 1850s. A major intellectual precursor was Licht en Schaduwbeelden uit de binnenlanden van Java, a controversial work attributed to physician and ethnologist Franz Wilhelm Junghuhn. The book presented contrasting intellectual positions, including materialism, deism, pantheism and orthodox Christianity, while treating nature and reason as sources of knowledge. Its challenge to revealed religion attracted criticism, but it was supported by members of the Amsterdam Masonic lodge Post Nubila Lux. Under the leadership of publisher Frans Christiaan Günst, the lodge's circle issued the periodical De Dageraad from 1 October 1855. On 12 October 1856, the magazine's circle established the association De Dageraad in Amsterdam. Rudolf Charles d'Ablaing van Giessenburg became its first chair. Forty-four men joined at the founding, but women were also admitted during d'Ablaing's chairmanship, reflecting his sympathy for feminist ideas. In 1857, the Rotterdam organization De Lichtstraal merged with De Dageraad. The association gradually moved away from its masonic origins and toward rationalism, natural science and criticism of revealed religion. The organization expanded under secretary and later chair Hendrik H. Huisman. It also benefited from the wider circulation of critical social writing, including work by Eduard Douwes Dekker, better known as Multatuli, although he was not formally a member. Internal disagreements nevertheless damaged the movement. In 1867, a group of deist members left to establish De Humaniteit. The original association's periodical was interrupted, weakening national coordination. De Dageraad temporarily adopted the name Het Vrije Onderzoek from 1873 to 1876. A joint 1875 manifesto with De Humaniteit called for cooperation among nonreligious people, separation of church and state, government responsibility for poor relief and compulsory primary education. De Humaniteit merged back into De Dageraad in 1878. The revitalized association became more democratic and public-facing. During the 1880s it increasingly embraced philosophical materialism and atheism, drawing on the work of Darwin, Haeckel, Büchner and Moleschott. Spinoza became an important symbolic and philosophical figure. Women freethinkers also played an increasingly visible role, and emancipation became an important part of the movement's public concerns. By 1882, membership had reached 357. From 1903 to 1933, membership grew from 613 to 2,700, supported by approximately forty regional branches. The organization debated how to respond to the growing political strength of confessional parties after the expansion of suffrage. Although some members supported independent political action, the central association rejected the creation of an officially affiliated party in 1920 in order to preserve internal pluralism. A separate electoral organization, Freethinkers into Parliament, contested elections in 1922 and 1925 but received little support and soon disappeared. The association's ideological position became more explicit in the interwar period. Its 1921 bylaws described freethinkers as taking an atheist position from the standpoint of reason. The government initially refused approval of this amendment, arguing that atheism threatened morality and public order. After debate, the association revised the wording while retaining its opposition to religious dogma and unquestionable authority; the revised bylaws were accepted in 1927. The association also supported campaigns encouraging people to leave the church and challenging the privileged role of religious institutions. Broadcasting gave the movement a wider audience. In 1928, members created the Vrijdenkers Radio Omroepvereeniging, or VRO. Its first experimental broadcast was interrupted during a discussion of Mussolini and freedom of thought, producing criticism from across the political spectrum. The VRO later received regular monthly airtime, but officials required that broadcasts avoid material considered offensive to believers. Programs were censored or cancelled, and the broadcasting license was withdrawn in 1936 after sustained pressure from confessional and nationalist forces. A 1932 blasphemy law and later restrictions on civil servants and public buildings further limited the association's activities. De Dageraad's publications also criticized Nazism and documented the persecution of German Jews. The German invasion in May 1940 brought the association's public work to an end. Branches were ordered to dissolve, records were destroyed or concealed, and De Vrijdenker ceased publication. The board continued to meet secretly. Several associated Jewish and atheist intellectuals were persecuted: Louis Fles died by suicide soon after the occupation began, Leo Polak died in Sachsenhausen in 1941, and Anton Constandse survived imprisonment. After liberation, De Dageraad was restored. Its board reconvened on 17 June 1945, and a large postwar conference followed in October. The revived magazine De Vrijdenker attracted prominent contributors and regained thousands of subscribers. The association sought cooperation with the Humanistisch Verbond and Humanitas, although differences remained between its more confrontational criticism of churches and the Humanistisch Verbond's emphasis on the social equality of nonbelievers. In 1957, De Dageraad became De Vrije Gedachte, with the stated connection to the promotion of independent thought. Its magazine was renamed Bevrijdend denken. The organization thereafter continued as a Dutch secular and freethought association rather than as a political party or commercial enterprise.
