Morgan's Canon

Coined by 19th-century British psychologist C. Lloyd Morgan, Morgan's Canon (more usually called Lloyd Morgan's Canon, or occasionally Morgan's Canon of Interpretation) remains a fundamental precept of comparative (animal) psychology. In its developed form it states that:

In no case is an animal activity to be interpreted in terms of higher psychological processes if it can be fairly interpreted in terms of processes which stand lower in the scale of psychological evolution and development.

In other words, Morgan believed that anthropomorphic approaches to animal behavior were fallacious, and that people should only consider behaviour as, for example, rational, purposive or affectionate, if there is no other explanation in terms of the behaviours of more primitive life-forms to which we do not attribute those faculties.
