Although the dominant strain in Judaism is that God is personal, there is an "alternate stream of tradition exemplified by ... Maimonides", who, along with several other Jewish philosophers, rejected the idea of a personal God. This reflected his belief in negative theology: that God can only be described by what God is not. Rabbi Mordecai Kaplan, who developed Reconstructionist Judaism and taught at the Conservative Jewish Theological Seminary of America, also rejected the idea of a personal God. Kaplan instead thought of God "as a force, like gravity, built into the very structure of the universe", believing that "since the universe is constructed to enable us to gain personal happiness and communal solidarity when we act morally, it follows that there is a moral force in the universe; this force is what the Constructionists mean by God", although some Reconstructionists do believe in a personal God. According to Joseph Telushkin and Morris N. Kertzer, Kaplan's "rationalist rejection of the traditional Jewish understanding of God exerted a powerful influence" on many Conservative and Reform rabbis, influencing many to stop believing in a personal God". According to the Pew Forum on Religion and Public Life's 2008 U.S. Religious Landscape Survey, Americans who identify as Jewish by religion are twice as likely to favor ideas of God as "an impersonal force" over the idea that "God is a person with whom people can have a relationship".
