To be very honest I dont particularly have a top ten on sages. The reason for this is that in my interpretation of a sage, it is someone whose knowledge and insights have a perrenial effect on millions of lives through the ages.
Therefore by that reckoning I feel a little stumped to pick who I believe the top 10 would be. To give you an example; If i went through religous figures and who has the most impact in the world by the sheer amount of believers in them then it would be 1. Buddah, 2.Allah followed by 3.Jesus Christ.
This in no way reflects which one of them I think is the greatest it just illustrates the difficulty if not presumptuousness on my part of putting them in a hierarchial pecking order based on the impact their insights have on me.
Also for me a sage does not represent only a philosophical or religous figure. to my mind there are many types of sages (impactors on humanity) business, science, marketing, technological etc.
All that i can offer in consolation of an exact answer is a humble request that you join me going forward as I shed some light on these figures, some of whom we havn't possibly heard of but whose impacts on our lives are monumental. (no pun intended)
