How much of the mental life which we attribute to ourselves and our fellow human beings should we attribute to other creatures, particularly those mammals to which we are most closely related in evolutionary terms, given that such creatures do not communicate with one another by means of anything resembling human natural language?
The paper approaches this question historically by considering the positions taken by Aristotle, Descartes, the post-Darwinians such as Romanes, the behaviorists down to Skinner, and contemporary philosophers such as Davidson and Fodor. A distinction is drawn between two concepts of consciousness: the biological/private which I argue we should not hesitate to attribute to all warm-blooded vertebrates and the linguistic/social which is exclusively human.
The concept of consciousness as biological and private is the 'consciousness' of traditional introspective psychology and of 'Is consciousness a brain process?' (Place 1956). It comprises the phenomena of selective attention, conceptualization, mental image formation, emotional reaction and motivation. The concept of consciousness as linguistic and social is the consciousness of Hegel, Marx, Vygotsky, Skinner and much contemporary philosophical psychology. It consists of an integrated system of propositional attitudes (beliefs) all of which are either formulated or susceptible to formulation as sentences in natural language (Skinner's "contingency-specifying stimuli" or "rules").
