Man is the only organism known to use both the analogic and the digital modes of communication. The significance of this is still very inadequately understood, but can hardly be overrated. On the one hand there can be no doubt that man communicates digitally. In fact, most, if not all, of his civilized achievement would be unthinkable without his having evolved digital language. This is particularly important for the sharing of information about objects and for the time-binding function of the transmission of knowledge. And yet there exists a vast area where we rely almost exclusively on analogic communication, often with very little change from the analogic inheritance handed down to us from our mammalian ancestors. This is the area of relationship. Based on Tinbergen (1953) and Lorenz (1952), as well as his own research, Bateson (1955) has shown that vocalizations, intention movements, and mood signs of animals are analogic communications by which they define the nature of their relationships, rather than making denotative statements about objects. Thus, to take one of his examples, when I open the refrigerator and the cat comes, rubs against my legs, and mews, this does not mean “I want milk” — as a human being would express it — but invokes a specific relationship, “Be mother to me,” because such behavior is only observed in kittens in relation to adult cats, and never between two grownup animals. Conversely, pet lovers often are convinced that their animals “understand” their speech. What the animal does understand, needless to say, is certainly not the meaning of the words, but the wealth of analogic communication that goes with speech. Indeed, wherever relationship is the central issue of communication, we find that digital language is almost meaningless. This is not only the case between animals and between man and animal, but in many other contingencies in human life, e.g., courtship, love, succor, combat, and, of course, in all dealings with very young children or severely disturbed mental patients. Children, fools, and animals have always been credited with particular intuition regarding the sincerity or insincerity of human attitudes, for it is easy to profess something verbally, but difficult to carry a lie into the realm of the analogic.
