Being sentient means to have the capacity to have positive and negative experiences, such as feeling pain and pleasure. This applies at the very least to all animals with centralised nervous systems. Sentient beings have their very own unique personalities. We should refer to them as “he/she”, “them/they” or by species. The words “it” or “thing” should not be used to refer to an animal, and “who” is used rather than “that”. If you do not know the gender, then choose one: “he” or “she”. Even if your gender choice is wrong, it is more respectful than “it”. This is an important way of demonstrating the respect we ask others to afford all animals.
Before we look at possible answers, we should try to establish an ethical baseline we all can agree on and work with. Most but not all people will accept that it is wrong to intentionally inflict harm onto others with the exception of acting in self defence. Intentionally harming other people is morally seen not acceptable. Violence is generally not regarded as normal behaviour, as it obviously can cause harm. It seems natural to most of us to help others, who have been harmed or are about to be harmed. But what drives us to help? And where does empathy and compassion come from?
