This page has a quote from R. B. Fuller on personal integrity along with a photograph.  

“The political and economic leaders of humanity are not in

final examination; it is the integrity of each individual

human that is in final examination.  On personal integrity

hangs humanity’s fate.  You can deceive others, you can

deceive your brain-self, but you can’t deceive your mind-

self-for mind deals only in the discovery of truth and the

interrelationship of all the truths.  The cosmic laws with

which mind deals are noncorruptible.” 

R. Buckminster Fuller, The Critical Path
