He received from
MIT a
BS in 1961 and a
PhD in 1965 under the supervision of
Francis E. Low. After two post-doctoral appointments as a research associate at the
University of Illinois at Urbana-Champaign (1965-7) and the
University of Toronto (1967-8), he became a physics professor in 1968 at Toronto until his retirement in 2005. He is now professor emeritus. He is a fellow of
St. Michael's College,
University of Toronto, the
Origins Institute at
McMaster University and Institute of Biocomplexity and Informatics at the
University of Calgary. While active at the
University of Toronto, in addition to math-based physics courses he taught an interdisciplinary course –
The Poetry of Physics – which led to his collaboration with
Marshall McLuhan, and his research in media ecology and the evolution of language. His best known works are
The Alphabet Effect – based on a paper Logan co-authored with McLuhan – which develops the hypothesis that the
alphabet, codified law, monotheism, abstract science and deductive logic form an autocatalytic set of ideas that developed uniquely between 2000 BC and 500 BC between the
Tigris-Euphrates river system and the
Aegean Sea;
The Sixth Language: Learning a Living in the Internet Age which deals with the hypothesis that speech, writing, math, science, computing and the Internet form an evolutionary chain of languages;
The Extended Mind: The Emergence of Language, the Human Mind and Culture develops a model for the
origin of language, the human mind and culture using ideas from
The Sixth Language. Logan has also been chief scientist at Strategic Innovation Lab at
OCAD University in Toronto, Ontario since 2007, and a senior fellow at the university's Strategic Innovation Lab (sLab). Part of his work at OCAD involved a language-based project to change popular attitudes about the environment, which resulted in the coining of the word "
depletist". In September 2010, Logan founded the McLuhan Legacy Network, a non-profit organization based in Toronto dedicated to renewing the legacy of Marshall McLuhan and celebrating the centenary of McLuhan's birth in 2011. Logan's work is influenced by
Marshall McLuhan,
Harold Innis,
Alvin Toffler,
Stuart Kauffman and
Terrence Deacon. ==Awards and honors==
