"Like universalism, secularism was important to modern Jewish social thought. "Jewish secularism is a revolt grounded in the tradition it rejects," argues David Biale, citing Isaac Deutscher's often-quoted remark about "the non-Jewish Jew," made in a 1954 speech. The "Jewish heretic who transcends Jewry belongs to a Jewish tradition, Deutscher asserted. Although Deutscher had his eye on European intellectuals, including Spinoza, Marx, Freud, Trotsky, and Rosa Luxemburg, the same could be said of American radical thinkers and activists such as Emma Goldman, who celebrated the Day of Atonement, the holiest night of the Jewish year, at the anarchists' festive Yom Kippur Ball. Individuals such as these moved beyond the confines of Jewry, crossing boundaries they considered too narrow. "Their minds matured where the most diverse cultural influences crossed and fertilized each other, Deutscher wrote. They lived on the margins or in the nooks and crannies of their respective nations. "They were each in society and yet not in it, of it and yet not of it." Like their European forebears in this tradition, pioneer Jewish women's liberationists in the U.S. were well assimilated into the culture of their times, but nevertheless, in disclosures to this author and at public events related to this project, they acknowledged a sense of difference based on their ethnicity and gender. This otherness helped take these activists "beyond the boundaries of Jewry," in Deutscher's words, enabling them to "rise in thought above their societies, above their nations, above their times and generations... to strike out mentally into wide new horizons and far into the future.""
