2) Isaac Newton
3) Jesus Christ
Here is the explanation on why Jesus Christ was not ranked first,
Did you catch that? If people who identified themselves as Christians actually followed the teachings of Christ more substantially, then Jesus would be considered more influential. Of course, this list means nothing in the whole scheme of things. It is merely one man's opinion, but it does get you thinking.
"It is not uncommon for people to wonder why Jesus is not ranked first on this list. As far as the way the list appears on this web page, the answer is simple: We have reproduced Hart's list in exactly the order he wrote it. But it is true that many people, both Christians and secular historians, would have ranked Jesus first on a list of the world's most influential people. Hart said that he himself would have ranked Jesus first, if all the people who today identify themselves as Christians actually followed Jesus's teachings more substantially. He considers contemporary Muslims more influenced by Muhammad than contemporary Christians are by Jesus.
Also, Hart's outlook was essentially secular in outlook. He did consider the doctrinal role of Jesus in human salvation as taught by Christianity. Muhammad, on the other hand, carved out an actual, geographic empire during his lifetime. Christians as well as historians agree that Jesus himself conquered no lands and led no armies during his lifetime."
