In this article in Aeon.com, Robert Twigger writes about the rise of the monopath in our society. The term refers to a person who focuses on one thing and becomes an expert. Such people are widely respected in their professions for having one-track minds. In contrast is the polymath who has read and studied widely in many different arenas.
We can point to two individuals who are "Renaissance men," able to speak on any subject and provide a raft of thoughts, quotations, and stories. Leonardo da Vinci is a perfect example of a polymath able to master intellectual, artistic, and physical pursuits. Ken Wilber comes to mind as another thinker whose range of knowledge and insight is astonishing. His integral spirituality is well worth looking into, thanks to its sweep and multidimensional wisdom.
