"We have learned by sad experience that it is the nature and disposition of almost all men, as soon as they get a little authority, as they suppose, they will immediately begin to exercise unrighteous dominion." --D&C 121:39Pretty apt isn't it? Now for a more secular source:
"Power corrupts, and absolute power corrupts absolutely."Speaking of which, I have in my hot little hands a copy of the Buttars letter in its entirity. I am currently debating the ethics of posting a scan of it on the internet.
