- the physio-animal mind has specific methods of "thinking." These are entirely reactive; animal experimentation—rats, dogs, etc.—is experimentation on and with precisely this mind and little more. It is a fully conscious mind. There is no period in the life of the organism from conception to death when this mind is not awake, observing, and recording perceptics. This is the mind of a dog, cat or rat and is also the basic mind of a man so far as its operating characteristics are concerned. (DTOT, p. 24)
