History and Terminology
B. P. Wiesner and Robert H. Thouless first proposed the term "psi" in 1942 as a more general term to include both extrasensory perception and psychokinesis. The original terminology proposal divided psi into psi-gamma, for cases of cognition, and psi-kappa, for cases of action. These terms were later modified into "passive psi" and "active psi".
In 1952, John W. Campbell proposed the term "psionics", from psi (‘psyche’) and the ending -onics from electronics (machine), which implied that the paranormal powers of the mind could be made to work reliably.

Famous quotes containing the word history:
“You that would judge me do not judge alone
This book or that, come to this hallowed place
Where my friends’ portraits hang and look thereon;
Ireland’s history in their lineaments trace;
Think where man’s glory most begins and ends
And say my glory was I had such friends.”
—William Butler Yeats (1865–1939)
