"The greater always includes the lesser, but the reverse is never true."
This is what I told myself often in the past, when in a situation with literal minded "believers". My beliefs could include theirs, encompass them, and embrace them in an esoterica manner.
I do question though whether the greatest minds of the Church every thought the Earth was flat. The greatest minds -- have always know that the Earth was round, and that it revolved around the Sun. The pragmatic ones just shut their mouths, to preserve and prolong their own existence on this mortal coil.
