The golden rule, when applied to one’s life, is bidirectional. By this i mean that not only do you do for others as you would have them do unto you, but you must then do or not do for yourself as you would do or not do for others respectively. There are vastly life-changing implications of this. Would you poor alcohol down the throat of a young child? Would you try to feed others fast food? If you could help it, would you let people do things that they would have any possibility of regretting afterwards? In this age, we need a new golden rule to apply after one understands the classical golden rule. Perhaps we can call it the “diamond” rule: Do TO yourself as you would do to others. Of course this requires adoption of the golden rule as a prerequisite, but assuming that has been realized, the implications are readily apparent.
*Note* When i refer to the golden rule, i don’t apply it to every small detail (e.g. i like death metal, so i will assume and act as though every one else does too). I take the rule to be: I want to be treated according to my personal desires and aversions, and so i should treat others likewise. This is the way in which i use the term here.
