Here, in a July 10, 1893 letter, he weighs-in on the priesthood:
Come, be men! Kick out the priests who are always against progress, because they would never mend, their hearts would never become big. They are the offspring of centuries of superstition and tyranny. Root out priest craft first. Come, be men! Come out of your narrow holes and have a look abroad. See how nations are on the march! Do you love man? Do you love your country? Then come, let us struggle for higher and better things; look not back, no, not even if you see the dearest and nearest cry. Look not back, but forward!
