Aaron David Gordon, was a Zionist ideologue and the spiritual force behind practical Zionism. He founded the "Ha'poel Hatzair" ("the Young Worker") movement that set the tone for the Zionist movement for many years to come. Influenced by Tolstoy and others, it is said that in effect he made a religion of labor. However, he himself wrote in 1920, "Surely in our day it is possible to live without religion." Wikipedia
