"Those angry will be happy again, and those wrathful will be cheerful again, but a destroyed nation cannot exist again, the dead cannot be brought back to life. Therefore, the enlightened ruler is prudent, the good general is cautious. This is the Way of securing the nation, and preserving the army." Sun Tzu
Let's dig deeper. The quote could also imply the temporary state that is life itself. You and I are here now but we won't be here for very long. Therefore, to cause pain and suffering to ourselves and those around us is rather presumptuous and laughable given our ridiculously short time and limited scope on earth.
Ultimately the path leads to one focused on caring for each other, if only to make life a little more bearable for another fellow human being. Sadly, some people don't even get this far before they pass away again.
Primum non nocere is a Latin term that means "first, do no harm." This is a famous motto for the medical profession. (In recent history, Google has adopted it as well. They have since become the most valuable public company in the world.) The Hippocratic Corpus states, "The physician must have two special objects in view with regard to disease, namely, to do good or to do no harm."
According to Hippocrates, a prudent and cautious approach is how disease should be handled. To me, a disease is analogous to a difficult problem, namely, an enemy! How you manage your enemy should rest on two options: to do good or to do no harm.
In other words, make sure your strategy will make the situation better, and if it doesn't, then do nothing at all until you find a proper strategy. Don't try to push through a bad strategy because it is a harmful strategy. Active inaction is indeed a viable strategy, even if the only benefit is that it doesn't make a bad situation worse.
Hippocrates lived 100 years after Sun Tzu but resided halfway across the globe. Hippocrates didn't steal his idea from Sun Tzu but both philosophers stole my heart with their wisdom. Universal wisdom can come from anyone, anywhere, and at anytime.
Therefore, go out out there and be prudent, be cautious, and be wise for yourself, for those you love, and even for those you love to hate. Godspeed.
