I stumbled upon this quote by Albert Jay Nock, a devotee of Voltaire.
"The only thing that the psychically-human being can do to improve society is to present society with one improved unit. In a word, ages of experience testify that the only way society can be improved is by the individualist method which Jesus apparently regarded as the only one whereby the Kingdom of Heaven can be established as a going concern; that is, the method of each one doing his very best to improve one."
I'll have to find more of Nock's work. It will be good reading during the 100-day party. It is change I can believe in.
