Truth is a personal journey of discovery. It is a relative perception and only you can know it and express it for yourself. The dogma of others can and often is in contradiction to what you know to be true for yourself. The beliefs of the merchant and priestly casts can and usually are at odds with the world view of other archetypes such as the mother, artist, musician, sage etc.
If somebody paints themselves as an authority figure and tells you that a cat is a dog, will you be fooled? A honorable man cannot agree with something that he knows just ain't so.
