A true man believes with his whole judgment, with all the illumination and discernment that is in him, and has always so believed. A false man, only struggling to "believe that he believes," will naturally manage it in some other way.
 Thomas Carlyle, On Heroes, Hero-Worship, and The Heroic in History (1841). copy citation

Context

“The sorriest sophistical Bellarmine, preaching sightless faith and passive obedience, must first, by some kind of conviction, have abdicated his right to be convinced. His "private judgment" indicated that, as the advisablest step he could take. The right of private judgment will subsist, in full force, wherever true men subsist. A true man believes with his whole judgment, with all the illumination and discernment that is in him, and has always so believed. A false man, only struggling to "believe that he believes," will naturally manage it in some other way. Protestantism said to this latter, Woe! and to the former, Well done! At bottom, it was no new saying; it was a return to all old sayings that ever had been said. Be genuine, be sincere: that was, once more, the meaning of it.” source
