Too often an LDS perception of art is equated with didacticism: we create because we are trying to teach. This desire to teach can often lead to pride, which leads to a loss of the Spirit. Viktor Shklovsky, a Russian Formalist who has had significant thought on my thinking and passion about the arts, wrote about poetry as being wrought with paradox. Something is poetic, because it is at ends with itself. This creates a place where the experience of the art cannot be considered didactic, yet the audience is forced to manage their way through the disparity. Among other things, it simply makes for a richer experience. (I've over simplified Shklovsky—and perhaps misappropriated him—but what follows is what I'm really concerned with).
In my view, an LDS world view is wrought with conflict and contradiction. This is the beginning of a list of these complexities inherent within Mormonism which should enrich our art.
1. That Paul says the Spirit is life but the flesh is death (that we are to overcome the carnal sensual natural man), yet the first and most foundational commandment given is to multiply and replenish the Earth. The only way to do this is through embracing the flesh (I'm not talking about marriage at all. Of course this is only to happen within th bonds of marriage, but it is a commandment to 1. get married, and 2. cleave unto our spouses). The goal (Spirituality and Eternal Lives) is only attainable through the only thing that is set in opposition to it (flesh is in opposition to the Spirit, yet only through being sensual, carnal, and 'natural' can we fulfill the commandment of the Spirit to obtain Eternal Lives).
2. Mainstreaming vs. being a peculiar people
3. Being learned and reading the best books vs. being humble and ignorant (like Adam and Eve), as a child—submissive, easy to be entreated, obedient.
4. Prosperity in the land vs. giving away all we own to follow the Savior (the eye of a needle vs. the Nephites promises).
5. The desire to teach vs. the desire to bare testimony. The desire to entreat to a change of behavior, versus express about our own behavior.
These are a starting point. I welcome your additions. What paradoxes do you see in Mormonism?
