1. axiom postulated by British psychologist C.
Lloyd Morgan (1852-1936) that the best theory
is the simplest one that also accounts for all the known facts. Morgan’s canon
was a restatement of Occam’s razor
from the late nineteenth century that animal behavior
should not be attributed to intention and forethought; animal behavior
should be interpreted as the simplest action
unless there is ample reason to consider otherwise. This was Lloyd Morgan’s reaction to the anthropomorphism
of this time.
