How much do we value other people, and how much should we value other people? At the core of ethics lies this question, and philosopher Peter Singer addresses it in his book The Most Good You Can Do. Singer refers to Canadian philosopher Richard Keshen’s ideas to build his vision of what ethics look like in an age of reason and tackles questions of how we should think about other people. In his book Singer writes, “At the core of the reasonable person’s ethical life, according to Keshen, is a recognition that others are like us and therefore, in some sense, their lives and their well-being matter as much as our own.”
This piece of advice is very similar to the Golden Rule, but with one notable distinction. The Golden Rule puts us at the center, focusing on how we want to be treated, and then expanding outward. Singer’s foundation for an ethical person starts with other people and a recognition that the lives of others are just as important in the world as our own life. It builds on common humanity and pushes past areas where see human ethics frequently fall short such as, tribalism, merit, and perceived responsibility. If we cannot start from a place where we accept that other people’s lives are as valuable as our own, we cannot move forward with truly equitable ethical foundations.
Singer’s ethical base also reminds me of childhood developmental studies and Theory of Mind, which focuses on a young child’s early recognition that other children and people have thoughts and feelings. This recognition builds until we are able to perceive, predict, and interpret the thoughts, feelings, and ideas of others. From our own consciousness we can begin approaching other people as if they are rational conscious individuals just like us, even though we can never see their consciousness or prove that they have thoughts just like we do. Ultimately, Theory of Mind, a recognition of conscious thought in other people (often also projected onto other living and even inanimate objects around us) begins to shape the ethical foundation of our life.
This seems to be built into Singer’s worldview through recognition and reflection of life and consciousness. On a recent episode of Sam Harris’s podcast, Waking Up, guest Yuval Noah Harari discussed Rousseau who said, “I think, therefore I am,” but he was critical of Rousseau’s fictitious “I,” or the self created by Rousseau out of nowhere and built on in story. Harari explained that the conclusion Rousseau should have reached is simply, “Thought exists, therefore thought exists.” This view does not diminish the reality of our consciousness, but helps us understand that the “I” discussed by Rousseau is simply the story that thought creates. We know that thought exists so it is not unreasonable to believe that others can think, and if others think and can build their own story to create a fictional “I,” then Singer’s ethical foundation still exists and is perhaps bolstered as we recognize the stories we tell ourselves and as we accept that our thought is in no way fundamentally different from the conscious thought of others which gives rise to our imaginary “I.” Ultimately, we must realize that we are limited in how we experience the world and that others experience the world in the same way. Increasing our ability to think of others and interpret the stories they create for themselves helps us to further our ethical thinking and behavior.
