infrahuman

But the infrahuman world may also be judged after the analogy of our fundamental faculties.

In the light of these results, it is obviously desirable that all studies of infrahuman organisms, but especially those of the various primates, should be made to contribute to the solution of our human problems.

Never before has a curve of learning like this been obtained from an infrahuman animal.

In other words, it is wholly at variance with the principle of trial and error exhibited by many infrahuman organisms.

To me it seems that thoroughgoing knowledge of the lives of the infrahuman primates would inevitably make for human betterment.
