# Isaac La Peyrère

Isaac La Peyrère (French pronunciation:; 1596–1676), also known as Isaac de La Peyrère or Pererius, was a French-born theologian, writer, and lawyer. La Peyrère is best known as a 17th-century predecessor of the scientific racialist theory of polygenism in the form of his Pre-Adamite hypothesis, which offered a challenge to traditional Abrahamic understandings of the descent of the human races as derived from the Book of Genesis. In addition to this, La Peyrère anticipated Zionism, advocating a Jewish return to Palestine, within the context of premillennialist Messianic theology. He moved in prominent circles and was known for his connections to the Prince of Condé and the abdicated Queen Christina of Sweden. Born to a Huguenot family, possibly of Portuguese Jewish converso or Marrano heritage,$^{:22-23}$ La Peyrère was pressured to renounce his views and publicly converted to the Catholic Church towards the end of his life, though the sincerity of this conversion has been questioned.

## Biography
### Background

La Peyrère's name is sometimes given in Latin as "Pererius", which is a version of Pereira.
He was born in Bordeaux, France, in a socially prominent family to parents Bernard La Peyrère and Marthe Malet, with eight siblings, among whom his brother, Abraham La Peyrère, was most notable. His father was the private secretary to Jacques II de Goyon de Matignon, Maréchal de France, while on his mother's side, his grandfather, was General Treasurer to the Royal House of Navarre.$^{:5}$
Both sides of La Peyrère's family were Calvinists, and many Bordeaux Protestants were suspected of being Marrano, or "secret Jews."$^{:5}$ While questions exist regarding a Jewish heritage, Richard Popkin presents evidence to the argument, that La Peyrère was of Marrano ancestry on his mother's side.$^{:22-25}$
La Peyrère was trained to be a lawyer.$^{:5}$

### Condé and Christina of Sweden

La Peyrère served as secretary to the Prince of Condé, on whose orders he lived for one month in 1654, in a house in the Southern Netherlands adjoining that of the recently abdicated Queen Christina of Sweden. Christina is said to have financed the anonymous publication of Prae-Adamitae. During this time both Christina and La Peyrère met with Menasseh Ben Israel, who was later invited by Oliver Cromwell's government to England to negotiate the readmission of Jews to that country. Menasseh became a convert to La Peyrère's belief that the coming of the Jewish Messiah was imminent. La Peyrère also argued that the Messiah would join with the king of France (that is, the Prince of Condé, not Louis XIV of France) to liberate the Holy Land, rebuild the Temple and set up a world government of the Messiah with the king of France acting as regent. It has since emerged that, in fact: "Condé, Cromwell and Christina were negotiating to create a theological-political world state, involving overthrowing the Catholic king of France, among other things."$^{:407}$

### Pre-Adamite hypothesis

In his Prae-Adamitae, published in Latin in 1655, and in English as Men Before Adam in 1656, La Peyrère argued that Paul's words in Chapter 5, verses 12-14 of his Epistle to the Romans should be interpreted such that, "if Adam sinned in a morally meaningful sense there must have been an Adamic law according to which he sinned. If law began with Adam, there must have been a lawless world before Adam, containing people."$^{:52–53}$ Thus, according to La Peyrère there must have been two creations: first the creation of the Gentiles and then that of Adam, who was father of the Jews. The existence of pre-Adamites, La Peyrère argued, explained Cain's life after Abel's murder which, in the Genesis account, involved the taking of a wife and the building of a city. This account of human origins became the basis for 19th century theories of polygenism and were espoused by those trying to justify racism in the New World.$^{:228}$ This polygenesis of the Gentiles was his method of explaining the existence of the Negroes, Chinese, Eskimos, American Indians, Malays and other people groups being discovered.
In 19th-century Europe, polygenism and Pre-Adamism were attractive to those intent on demonstrating the inferiority of non-Western peoples, while in the United States those attuned to racial theories who found it unattractive to contemplate a common history with non-Whites, such as Charles Caldwell, Josiah C. Nott and Samuel G. Morton, also rejected the view that non-whites were the descendants of Adam. Morton combined pre-Adamism with cranial measurements to construct a theory of racial difference that justified slavery. As Michael Barkun explains,
   In such an intellectual atmosphere, Pre-Adamism appeared in two different but not wholly incompatible forms. Religious writers continued to be attracted to the theory both because it appeared to solve certain exegetical problems (where did Cain's wife come from?) and exalted the spiritual status of Adam's descendants. Those of a scientific bent found it equally attractive but for different reasons, connected with a desire to formulate theories of racial difference that retained a place for Adam while accepting evidence that many cultures were far older than the few thousand years humanity had existed, according to biblical chronology. The two varieties differed primarily in the evidence they used, the one relying principally on scriptural texts and the latter what passed at the time for physical anthropology.$^{:153}$

### Later life

La Peyrère's pre-Adamite contentions were fiercely criticized by Protestant, Jewish and Catholic authorities. In 1656, after a storm of indignation the Prae-Adamitae was publicly burned in Paris. In particular, La Peyrère fell foul of the Catholic Church, while in the Spanish Netherlands which was then under the Habsburgs. Here, he was arrested and held in prison for six months and only released after renouncing his views and converting to the Catholic faith. He subsequently went to Rome and begged Pope Alexander VII for forgiveness, retracting his earlier views formally. Following this La Peyrère became a lay member of the Oratory of Jesus in Paris and lived out the rest of his life, from 1659 until 1676. The sincerity of his conversion was later questioned. Pierre Bayle, for example, published a letter in which his religious superior wrote that he "was always writing books that ... would be burned as soon as the good man died."
La Peyrère was influenced by Thomas Hobbes and was an influence on Baruch Spinoza. In his later life, La Peyrère was an influence on fellow Oratory of Jesus member, Richard Simon, who has been called "father of the higher criticism."$^{:87}$Simon had a Jewish friend who was a follower of Sabbatai Zevi, and tried to have La Peyrere talk to him, but he showed no interest in the messianic claims.
