modified based on whether they served these higher purposes. This stance allowed a great variety of practice both in the past and the present. In "Classical" times, personal observance was reduced to little beyond nothing. The postwar "New Reform" lent renewed importance to practical, regular action as a means to engage congregants, abandoning the sanitized forms of the "Classical". Another key aspect of Reform doctrine is the personal autonomy of each adherent, who may formulate their own understanding and expression of their religiosity. Reform is unique among all Jewish denominations in placing the individual as the authorized interpreter of Judaism. This position was originally influenced by Kantian philosophy and the great weight it lent to personal judgement and free will. This highly individualistic stance also proved one of the movement's great challenges, for it impeded the creation of clear guidelines and standards for positive participation in religious life and definition of what was expected from members. The notion of autonomy coincided with the gradual abandonment of traditional practice (largely neglected by most members, and the Jewish public in general, before and during the rise of Reform) in the early stages of the movement. It was a major characteristic during the "Classical" period, when Reform closely resembled Protestant surroundings. Later, it was applied to encourage adherents to seek their own means of engaging Judaism. "New Reform" embraced the criticism levied by Rosenzweig and other thinkers at extreme individualism, laying a greater stress on community and tradition. Though by no means declaring that members were bound by a compelling authority of some sort – the notion of an intervening, commanding God remained foreign to denominational thought. The "New Reform" approach to the question is characterized by an attempt to strike a mean between autonomy and some degree of conformity, focusing on a dialectic relationship between both. The movement never entirely abandoned halachic (traditional jurisprudence) argumentation, both due to the need for precedent to counter external accusations and the continuity of heritage. Instead, the movement had largely made ethical considerations or the spirit of the age the decisive factor in determining its course. The German founding fathers undermined the principles behind the legalistic process, which was based on a belief in an unbroken tradition through the ages merely elaborated and applied to novel circumstances, rather than subject to change. Rabbi Samuel Holdheim advocated a particularly radical stance, arguing that the halachic Law of
