“Good then if we mean by it that quality which we assert to belong to a thing, when we say that the thing is good, is incapable of any definition…” – G.E. Moore, Principia Ethica.
The crux of reality and life for sapient beings revolves around the concepts of Good and Evil. For instance one may question whether the universe is mostly good, mostly evil, or neither. Individual actions are considered ethical if ‘good’ and immoral if ‘evil.’ Therefore the next step is to think through these two words and the relationship between them.
Like we found with the word ‘reality,’ philosophical dictionaries and encyclopedias tend to avoid defining the word ‘good’ per se. Dagobert Runes has a passable two part definition1:
1. In ethics, morally praiseworthy character, action, or motive.
2. Anything desirable, or that ought to be desired.
However, the words ‘praiseworthy’ and ‘desirable’ seem a bit circular rather than defining to me, and leave the real concern of relativity. After all a tyrant believes control of others is desirable, but it is not clear that makes for a ‘good.’ Webster’s dictionary has a half-column, 58 meaning entry for the word ‘good.’ None is more exact or more useful than these.
Aristotle thought of a ‘good’ as something which leads to happiness, but that seems insufficient for more general use. Accordingly I will again suggest my own definition:
Good is that which contributes to the happiness, well-being, longevity, pleasure, or knowledge of oneself and others or at least does not diminish these for others; or which promotes existing non-human reality in the universe. Evil then is simply its negative.
No one need accept this definition, but the alternative is to rely on one’s own intuitive definition of good. G.E. Moore thinks it is too basic a concept (like ‘yellow’) to be truly definable. This is troubling given the foundational nature of good and evil in much of practical philosophy, but the reader can at least get a sense of my use of those essential words from my definition.
