One of the great tasks of Mortimer Adler’s illustrious life was his search for a watertight proof of the existence of God. Adler believed that his search had been successful. Adler spent years studying the classic proofs of God’s existence, especially Aquinas’s Five Ways, and found shortcomings in all of them, as conventionally understood. But he thought that some of them contained ideas which, if properly developed, could be improved, and he continued to search for a satisfying and logically unassailable proof. Toward the end of the 1970s, he believed he had arrived at such a proof, which he presented in his historic work, How to Think about God (1980). In the writings assembled in How to Prove There Is a God, Adler gives us his approach to the question of God’s existence in fresh and popular form. He defends his position against critics, both believers and skeptics. The book includes a transcript of one of Adler’s appearances on William Buckley’s Firing Line, Adler’s revealing interview with Edward Wakin, the exchange of views on natural theology between Adler and Owen Gingerich, and John Cramer’s eloquent argument that the trend of modern cosmology supports Adler’s early struggles with the question of God's existence.
Author

Numerous published works of American educator and philosopher Mortimer Jerome Adler include How to Read a Book (1940) and The Conditions of Philosophy (1965). This popular author worked with thought of Aristotle and Saint Thomas Aquinas. He lived for the longest stretches in cities of New York, Chicago, San Francisco, and San Mateo. He worked for Columbia University, the University of Chicago, Encyclopædia Britannica, and own institute for philosophical research. Born to Jewish immigrants, he dropped out school at 14 years of age in 1917 to a copy boy for the New York Sun with the ultimate aspiration to a journalist. Adler quickly returned to school to take writing classes at night and discovered the works of Aristotle, Thomas Aquinas, John Locke, John Stuart Mill, and other men, whom he came to call heroes. He went to study at Columbia University and contributed to the student literary magazine, The Morningside, (a poem "Choice" in 1922 when Charles A. Wagner was editor-in-chief and Whittaker Chambers an associate editor). Though he failed to pass the required swimming test for a bachelor's degree (a matter that was rectified when Columbia gave him an honorary degree in 1983), he stayed at the university and eventually received an instructorship and finally a doctorate in psychology. While at Columbia University, Adler wrote his first book: Dialectic, published in 1927. In 1930 Robert Hutchins, the newly appointed president of the University of Chicago, whom Adler had befriended some years earlier, arranged for Chicago’s law school to hire him as a professor of the philosophy of law; the philosophers at Chicago (who included James H. Tufts, E.A. Burtt, and George H. Mead) had "entertained grave doubts as to Mr. Adler's competence in the field [of philosophy]" and resisted Adler's appointment to the University's Department of Philosophy. Adler was the first "non-lawyer" to join the law school faculty. Adler also taught philosophy to business executives at the Aspen Institute. Adler and Hutchins went on to found the Great Books of the Western World program and the Great Books Foundation. Adler founded and served as director of the Institute for Philosophical Research in 1952. He also served on the Board of Editors of Encyclopædia Britannica since its inception in 1949, and succeeded Hutchins as its chairman from 1974. As the director of editorial planning for the fifteenth edition of Britannica from 1965, he was instrumental in the major reorganization of knowledge embodied in that edition. He introduced the Paideia Proposal which resulted in his founding the Paideia Program, a grade-school curriculum centered around guided reading and discussion of difficult works (as judged for each grade). With Max Weismann, he founded The Center for the Study of The Great Ideas. Adler long strove to bring philosophy to the masses, and some of his works (such as How to Read a Book) became popular bestsellers. He was also an advocate of economic democracy and wrote an influential preface to Louis Kelso's The Capitalist Manifesto. Adler was often aided in his thinking and writing by Arthur Rubin, an old friend from his Columbia undergraduate days. In his own words: Unlike many of my contemporaries, I never write books for my fellow professors to read. I have no interest in the academic audience at all. I'm interested in Joe Doakes. A general audience can read any book I write—and they do. Source: http://en.wikipedia.org/wiki/Mortimer...
