"Atheism … in its philosophic aspect refuses allegiance not merely to a definite concept of God, but it refuses all servitude to the God idea, and opposes the theistic principle as such. Gods in their individual function are not half as pernicious as the principle of theism which represents the belief in a supernatural, or even omnipotent, power to rule the earth and man upon it. It is the absolutism of theism, its pernicious influence upon humanity, its paralyzing effect upon thought and action, which Atheism is fighting with all its power."

“Anarchism is the only philosophy which brings to man the consciousness of himself; which maintains that God, the State, and society are non-existent, that their promises are null and void, since they can be fullfilled only through man's subordination.”

“America had declared war with Spain.... It did not require much political wisdom to see that America's concern was a matter of sugar and had nothing to do with humanitarian feelings. Of course there were plenty of credulous people, not only in the country at large, but even in liberal ranks, who believed in America's claim. I could not join them. I was sure that no one, be it individual or government, engaged in enslaving and exploiting at home, could have the integrity or the desire to free people in other lands.”

“No sacrifice is lost for a great ideal!”

“The period of the actual revolution, the so-called transitory stage, must be the introduction, the prelude to the new social conditions. It is the threshold to the NEW LIFE, the new HOUSE OF MAN AND HUMANITY. As such it must be of the spirit of the new life, harmonious with the construction of the new edifice.”

“It is characteristic of theistic "tolerance" that no one really cares what the people believe in, just so they believe or pretend to believe.”

“The custom of procuring abortions has reached such appalling proportions in America as to be beyond belief... So great is the misery of the working classes that seventeen abortions are committed in every one hundred pregnancies.”
