Who would you say is the most influential philosopher of all time? I am taking about a philosopher who has not just made a fundamental impact on Western philosophy, but also on Eastern philosophy, and all the other ones of which I am not aware. I am also not taking about the best, greatest, or most known, loved, cited, quoted, or recognized. My question is solely based on influence, whether it was good, bad, both, or neither.
