Perhaps naive if someone focuses on the first part on the sentence and not the latter half and the second sentence. I assume too my understanding of what truth is to vary from what I suppose I would refer to as a 'common' understanding. People discover truth and until they do they often act in ways that do not align with truth hence, slavery and so on. Some people still think slavery is good and that women are inferior to men.
