 Disappointed by the unenthusiastic response his work got from the workers, Comte launched an Appeal to Conservatives in 1855. The next year, he published the first volume of a work on the philosophy of mathematics announced in 1842, under the new title of Subjective Synthesis, or Universal System of the Conceptions Adapted to the Normal State of Humanity. Increasingly occupied by his function as High Priest of Humanity, he sent an emissary to the Jesuits in Rome proposing an alliance with the ‘Ignacians’.
