Morgan's Canon - Evaluation

Evaluation

As the study of animal cognition has become popular, a disciplined use of Lloyd Morgan's canon has become more and more important. D.A. Dewsbury called Morgan's Canon "perhaps, the most quoted statement in the history of comparative psychology" and Frans de Waal echoed this in The Ape and the Sushi Master: "perhaps the most quoted statement in all of psychology". It has played a critical role in the growth of the prestige of behaviourism in twentieth century academic psychology.

Lloyd Morgan's Canon is usually thought of as a special case of Occam's razor by virtue of its presupposition of simplicity that lower level interpretations are more parsimonious than higher level ones. See also the use of Morgan's canon in Biology at Occam's Razor.

Famous quotes containing the word evaluation:

    Evaluation is creation: hear it, you creators! Evaluating is itself the most valuable treasure of all that we value. It is only through evaluation that value exists: and without evaluation the nut of existence would be hollow. Hear it, you creators!
    Friedrich Nietzsche (1844–1900)

    Good critical writing is measured by the perception and evaluation of the subject; bad critical writing by the necessity of maintaining the professional standing of the critic.
    Raymond Chandler (1888–1959)
