==Personal life==
In 1925, Morris married Gertrude  E. Thompson, with whom he had a daughter, Sally Morris Petrilli. In 1951, he married his second wife, Ellen Ruth Allen, a psychologist.

===Unity of Science Movement===
While on sabbatical from the University of Chicago in 1934, Morris traveled abroad, visiting Europe and meeting working philosophers such as [[Bertrand Russell]] and members of the [[Vienna Circle]], like [[Rudolf Carnap]], [[Otto Neurath]], and [[Moritz Schlick]]. Morris was greatly impressed with the logical positivist (logical empiricist) movement. While presenting a paper in [[Prague]] at the Eighth International Congress of Philosophy, he discussed his hopes for a union of pragmatism and positivism.<ref name="Reisch 2001" /> Sympathetic to the positivist's philosophical project, Morris became the most vocal advocate in the United States for Otto Neurath's "Unity of Science Movement".

During the 1930s, Morris helped several German and Austrian philosophers emigrate to the United States, including Rudolf Carnap in 1936. As a part of the "Unity of Science Movement", Morris worked closely with Neurath and Carnap to produce the ''[[International Encyclopedia of Unified Science]]''. As co-editor of the ''Encyclopedia'', Morris procured publication in America from the [[University of Chicago Press]]. His involvement with the ''Encyclopedia'' spanned for ten years when the project lost momentum in 1943.<ref name="Reisch 2001" /> Both Morris and Carnap found it difficult to keep the ''Encyclopedia'' alive due to insufficient funds. In the latter part of the 1940s, Morris was finally able to secure funding that allowed the project to last until its final publication in the 1970s.
