I rather think so. I have known a few, some who were successful plus some abysmal failures. The one common thread they had was an inflexible,narrow and closed mind, as if they were clinging desperately to this self-defeating doctrine lest they should morally and intellectually disintegrate.

Needless to say they were quite incapable of sharing,nay understanding other viewpoints that threatened {was gonna say conflicted} with their own.
