After the Second World War, African Spir fell into oblivion. In 1990, for the centennial of Spir's death in Geneva, the Geneva Public Library organized an exhibition of African Spir's corpus and published the analytical catalogue. Many of Spir's books have not been entirely sold and are still available in their first or second edition (in German, French, Italian, English, or Spanish translations). Presumably, due to the increasing interest in the argument at the beginning of the twenty-first century, a reprint of the Italian translation by Odoardo Campa in 1911 of Spir's "Moralität und Religion" (1874) has been published in 2008.
