Heresy is the life of a mythology, and orthodoxy is the death.
Joseph Campbell
I think vital religion has always suffered when orthodoxy is more regarded than virtue. The scriptures assure me that at the last day we shall not be examined on what we thought but what we did.
Benjamin Franklin
Orthodoxy is a relaxation of the mind accompanied by a stiffening of the heart.
Edward Abbey
The heterodoxy of one age will become the orthodoxy of the next.
Benjamin Fish Austin
The heresies we should fear are those which can be confused with orthodoxy.
Jorge Luis Borges
