Notes from Wikiquote
Based on a quote of Lucretia Mott, "… my convictions led me to adhere to the sufficiency of the light within us, resting on truth as authority, rather than “taking authority for truth.”", quoted in "Eminent women of the age" By James Parton et. al., (S.M. Betts & Company, 1868, p375).
