Isaac La Peyrére
Isaac La Peyrére (1596-1676) was a French philosopher and diplomat. Although brought up a Calvinist he was later forced to convert to Catholicism. His theological interests centred on the idea that Adam was not the first human, an viewpoint he expressed in Prae-Adamitae. He argued that there must have been two creations; first the creation of the gentiles and later that of Adam, as father of the Hebrews. He also cited Plato’s 9,000 years for Atlantis existing before Solon as adding justification for his theory.
It was the publication of his Pre-Adamite book, denounced as heretical, which led him to his enforced coversion to Catholicism. Some of his ideas are widely accepted today(a).
