The critical question for utilitarians is not ‘Is this natural or is this appropriate for humans?’ but rather ‘Will this make people’s lives go better?’ […] Objectors to utilitarianism often refer scathingly to the ‘utilitarian calculus’. However utilitarians are in one sense humane: they care ultimate about people’s well-being and not about feelings, or intuitions or attachment to symbols. Utilitarianism is a theory that shows concern for people through concern for their well-being.
