Life and Ethics: Singer, Plato, and Moral Philosophy

Self-Interest and Its Consequences for Society

The concept of self-interest, which is central to many of the themes in Peter Singer's work of non-fiction How Are We To Live?, has existed for several hundred years and has influenced many philosophers and their principles. This doctrine simply states that mankind is primarily motivated by an inherent concern for one's own well-being, and that virtually all actions, thoughts, and decisions are made to further one's particular interests. Political philosophers such as the 17th-century thinker Thomas Hobbes claimed that even seemingly altruistic acts of sacrifice and concern for the welfare of others can be reduced to principles of self-interest — that such sacrifice is merely preferred over the guilt one might feel at not having made it. Morally, such primal, instinctive principles of human governance lead to a self-absorbed culture (such as the one Singer identifies within contemporary Western society) whose ultimate function is merely to consume and to seek pleasure, primarily through the pursuit of monetary and technological assets. The moral worth of an act in such a society is determined by its fiscal value as it relates to the individual alone, and not to the greater good of society.

Such self-absorbed behavior contributes to the degradation of society, since everyone is living, acting, and interacting with others simply for their own benefit. The sociological and ecological crisis that Singer references is based on the fact that with fluctuating mores dictated by a host of individual self-interests, there is no true ethical fiber to hold community relations together. Therefore, Singer believes such a society is headed for inevitable disaster as a result of its disparate and conflicting interests. Self-interest is distinguished from selfishness by the fact that acts done to benefit others may still fall under the former term, even though the root cause of such actions is to benefit the person performing them. Selfishness, by contrast, is essentially defined as an act that benefits only the individual and no one else.

The answer to the question "How are we to live?" — which is the premise of Singer's book of the same name — is that we should live ethically and embrace that decision as the ultimate choice, one which will provide our lives with far more significance and lasting importance than the transient pleasures of money and technology. The pursuit of the latter represents only a restricted set of choices, particularly given their ephemeral nature and the fickleness of mankind. Meanwhile, committing one's life to the ethical choice frees one from the culture of self-interest and enables one to begin living for the benefit of others.

The Ring of Gyges: Morality Without Judgment

The Ring of Gyges is a mythological artifact that allegedly granted its bearer the power of invisibility. The ring is famously discussed in Plato's Republic as an illustration of the argument that no man is truly moral, particularly when freed from the responsibility of being judged by others. By donning the ring and becoming invisible, an individual would supposedly reveal the base nature of mankind by committing a series of immoral acts. The scope and nature of these acts varies with the particular philosophy applied to the bearer of the ring.

Utilitarian philosophy, for example, would have what is traditionally considered an immoral act — such as robbing a bank — committed and used for decidedly moral ends, such as feeding the starving poor in war-torn countries. The usefulness of the act would be judged by the positive effects of the benefit to the poor, which would conceivably outweigh the negative effects of wealthy individuals losing a fraction of their total holdings. Such actions might well be justified, particularly if the resources in question can be verified to come from dubious or even insidious sources, and if the charitable recipients can be confirmed to be genuinely in need. These two verifications would provide a sound moral rationale for the act in this particular instance.

However, most individuals, particularly in contemporary Western society, would probably act in their own self-interest — somewhat in keeping with the philosophy Hobbes described as inherent to human nature. In this scenario, morality is decided by the gain, pleasure, and self-interest of the individual wearing the ring. Such individuals would likely obtain this gain through illicit means, such as robbing a bank, and use their winnings for self-absorbed ends, acquiring material goods to satisfy personal desires. In this case, there is no compelling reason for the individual to act ethically, since the bearer of the ring is beyond the judgment — both literally and figuratively — of others, whose moral standards no longer constrain that individual.

Conclusion

Taken together, the frameworks offered by Singer, Hobbes, Plato, and Weston converge on a shared insight: that living well requires more than the satisfaction of personal desire. Self-interest, left unchecked, erodes both individual integrity and social cohesion. The Ring of Gyges reveals that true morality cannot depend solely on external judgment; the Rashomon effect reminds us that moral perception is always partial and subjective; and constructive moral dialogue offers the practical means by which individuals can move beyond self-absorption toward genuine ethical engagement. Singer's central answer — that we should embrace the ethical life as our ultimate choice — remains as urgent as ever.
