C. I. Lewis, who was at the time the department chair of philosophy at Harvard, eventually approved Weiss to work alongside Hartshorne for the remainder of the project. The first six volumes of Peirce's work would eventually be published between 1931 and 1935. Weiss was mainly responsible for the second, third, and fourth volumes. Two more volumes, both edited by Arthur Burks, would later appear in the 1950s. Teaching In 1931 Paul Weiss left Harvard and began teaching philosophy at Bryn Mawr. As Weiss explains, Bryn Mawr was at the time "the self-chosen destination of the most intellectual, intelligent, determined, and well-prepared young women in America." Some fifteen years later in 1946, Weiss was invited to teach at Yale for a term as a substitute for Brand Blanshard. He accepted and what began as a temporary job turned into a permanent position that lasted for twenty four years. He comments that his experience at Yale was quite different from Bryn Mawr. "I was there faced with men—no women were enrolled in the undergraduate school until more than two decades later—many of whom had just returned from military service. They were older, some having gone through searing experiences, no longer enjoying the cozy atmosphere of their preparatory schools. I seemed to be just the teacher they needed and wanted." Weiss remained at Yale until 1969 when he reached Yale's mandatory retirement age. Shortly after, he was offered the Schweitzer Chair of philosophy at Fordham University, but the offer was quickly retracted, allegedly due to Weiss's age. Weiss challenged Fordham's decision in an age discrimination lawsuit, but in the end he lost. In the early 1970s, Weiss began teaching at the Catholic University of America. In 1992 Weiss's contract with the university was not renewed. Again he felt that age discrimination played a role in the university's decision. Weiss and his son Jonathan, a lawyer and director of Legal Services for the Elderly in New York, challenged the Catholic University of America's decision. The Equal Employment Opportunity Commission investigated the case and eventually ruled in Weiss's favor. His contract with the Catholic University of America was renewed until 1994 when Weiss voluntarily retired. Philosophical work Weiss was responsible for founding the scholarly journal The Review of Metaphysics in 1947. He also went on to found a notable philosophical organization, the Metaphysical Society of America, in 1950. Among his philosophical works, Weiss is
