James Sully

James Sully (Bridgwater, 1842 – Richmond, 1923) was an English psychologist and philosopher who worked at the border between the philosophy of mind and the emerging scientific psychology. Raised in a Baptist family, he trained for the nonconformist ministry and studied at Göttingen and Berlin under Hermann Lotze and Hermann von Helmholtz. In 1871, however, he chose a literary and philosophical career instead.

Between 1892 and 1903 he held the Grote Chair of the Philosophy of Mind and Logic at University College London. He belonged to the associationist school, close in outlook to Alexander Bain, and wrote psychology textbooks, some among the first in English, such as The Human Mind (1892). His Illusions (1881) won praise from both Freud and Wundt, and his studies of childhood and laughter show his interest in mental development and emotion.

In 1898 he opened an experimental psychology laboratory at University College London, and in 1901 he was a founding member of the British Psychological Society. His lasting contribution lies in helping to establish psychology as an academic discipline in Britain, joining philosophical reflection with empirical observation.
