The above quote by McLuhan would apply to many of the faithful within the LDS church regarding the subject of Mormon history.

Just like a fish that can't see the water it's swimming in, we often cannot see the world around us. It takes someone with a different perspective, someone outside our hardened, well warn paradigm to point out our blind spots. Remember, our perception is our reality, it’s the world we live in, we often are not able to see our own learning opportunities, ironically, because we are living and staring at them every day.

Once we allow ourselves to become immersed in the environmental muse, filled with people with similar thinking, it becomes extremely difficult to see the world around us, or discern if your belief system is rational and well thought-out able to withstand scrutiny, or are we merely adhering to the powerful influences of tradition and cultural conditioning. It is very difficult to break out of a well-worn paradigm once fully ingrained. - D. Charle
