When we think of "ancient wisdom" we sometimes tend to associate the term with worthy epigrams, aphorisms and advice which has been transmitted to us through religious or high-brow academic media such as theology, philosophy (with a capital "P"), and other "ologies" or "osophies" of the ilk. What is lost therefore is the realisation that some of the best and most enduring maxims encapsulating such wisdom originated in, and endured because of, a basic common sense which is as important and relevant to us all today as it always has been. As such they belong to no particular ideological creed or discipline, but to humanity itself.
Taking as an arbitrary cut-off point for "ancient" to be the transition from BCE to CE in the western calendar, how many gems of sound advice from two millennia and longer ago are there which, when one thinks about it, should be taught today to the point that we are as familar with them as we are now with contemporary pearls of wisdom coincidentally surviving as religious or philosophical doctrine? The Book of Proverbs is a reservoir of some of these home-spun aphorisms familiar to many now outside the Judaic, Christian or Muslim faiths, but only because they were protected from extinction through the preservation of scripture by these faiths for religious reasons, not for their appeal to common sense.
How many of these nuggets' contemporaries however have also endured, despite not being so "protected", and did so because they were primarily sensible, not ever supporting or intended to support any ideology apart from that which promoted general common sense?
My curiosity was prompted after reading the advice attributed to Ptahhotep, a vizier in 5th Dynasty Egypt around 2,500BCE, which in our modern western society should now be compulsorily taught, I reckon, to everyone from birth;
"Be merry all your life. Toil no more than is required nor cut short the time allotted for pleasure. It offends the spirit to be robbed of its time. So waste not an hour more than you must taking care of your household. Wealth will come even if you indulge in your own wishes, but it will be useless if you are glum."
