A man protesting against error is on the way towards uniting himself with all men that believe in truth. There is no communion possible among men who believe only in hearsays. The heart of each is lying dead; has no power of sympathy even with things,—or he would believe them and not hearsays.
 Thomas Carlyle, On Heroes, Hero-Worship, and The Heroic in History (1841). copy citation

Context

“And now I venture to assert, that the exercise of private judgment, faithfully gone about, does by no means necessarily end in selfish independence, isolation; but rather ends necessarily in the opposite of that. It is not honest inquiry that makes anarchy; but it is error, insincerity, half-belief and untruth that make it. A man protesting against error is on the way towards uniting himself with all men that believe in truth. There is no communion possible among men who believe only in hearsays. The heart of each is lying dead; has no power of sympathy even with things,—or he would believe them and not hearsays. No sympathy even with things; how much less with his fellow-men! He cannot unite with men; he is an anarchic man. Only in a world of sincere men is unity possible;—and there, in the long-run, it is as good as certain.
