In my earlier article “Listen to Your Feelings“, I added the following section on the importance of beauty, after my friend Jason Van Boom alerted me to the important connection between beauty and moral reasoning (an insight Jason got from reading Hume of all people).
…it is through an emotional attraction to beauty that we are motivated to make moral judgments and to order our lives according to transcendent realities. Through the sense of beauty we are moved out of indifference to become emotionally invested in pursuing one outcome rather than another. For example, when Eve succumbed to the temptation to disobey God (Gen. 3:6), it was because the beauty of the tree and its effects (“pleasant to the eyes… desirable to make one wise”) captured her imagination with greater force than the beauty of remaining faithful to the will of God. That example might lead us to disparage the role of beauty in moral decision-making, and yet the same principle also works in the other direction as the Holy Spirit sanctifies our feelings and imaginations. Through a sense of Christ’s beauty, we become emotionally invested in following Him. For example, when we observe character traits in Bible characters and saints that are worthy of emulation, when we identify certain things as honorable or shameful, when our praise of God is rooted in heart-felt admiration, or when we order our actions based on a longing for outcomes that lie outside the scope of the present life but which are attractive to our imagination—all these things partly arise from a sense of “the beauty of holiness.” (Ps. 96:9) A rightly-ordered sense of beauty is thus central to the moral imagination of the believer.
