A highly developed mind 

“To have a highly developed mind but lacking in wisdom as an underlying guiding force [..] is a dangerous thing. Because that mind can create havoc for yourself and others. The more developed it (the mind) is, the more destructive it potentially is also. You find that also with some people who run countries. [..] some not all might be considered intelligent in conventional terms, yet their actions are very unintelligent.[..] so whatever they say or do is not connected to the realm of wisdom.”

Eckhard Tolle
