But suppose they were otherwise, what would it avail? The question is not, Can they reason? nor Can they talk? but, Can they suffer? (Bentham 1960:41 In) Although Bentham’s concern for animals is not unique to the period, it demonstrates not only the debt owed by Singer to his classical forerunner but it also takes the next step for him. If we must, as we have seen, forgo intelligence, the possession of language or similar ‘advanced’ human attributes and move to the minimal criterion of the capacity to suffer in order to allow for the equality of the human ‘hard’ cases like infants and imbeciles, then consistency requires that we must include animals since they too can suffer.

When considered in the light of the equality principle their interests relating to the mere avoidance of suffering will be enhanced by others stemming from these abilities as persons. 3 Animals and pain How does Singer come by these conclusions some of which, to the average reader, will seem exaggeratedly optimistic on behalf of animals? A part cause of initial scepticism will stem from his use of the term ‘person’. Clearly if the higher mammals can properly be so designated it would constitute a powerful weapon in the armoury of their equality with homo sapiens.

He describes the possession of conceptual thought without language as not ‘altogether inconceivable’. This isn’t very promising and suggests that it might at least strike readers as highly improbable. It seems strange then that we are so precipitately hurried into assessing concrete situations and invited to accept that it is indeed the case without any theoretical preamble to at least sugar the highly improbable pill into some degree of 36 THE UTILITARIAN BEGINNINGS plausibility. The examples do not speak for themselves.
