In his excellent book, The Evidential Power of Beauty: Science and Theology Meet, Thomas Dubay has a perceptive chapter titled, "Alive to Beauty." When I first read this chapter, I believe it was the first time I ever reflected on the connection between being keenly alive and an appreciation of beauty. Dubay states that "normal people love life," but notes that "a moment's reflection makes clear that there is in the human family a continuum from the keenly alive and responsive individual to the colorless, insensitive, and uninspired one." At one end of the spectrum are those who experience beauty intensely, and at the other are those who are bored with life and all that they see. Of the latter, Dubay says they are "incapable of being thrilled."
Dubay, following Thomas Aquinas, makes the case that beauty is related to truth and that it is objective. But, it is his insight that boredom is the result of excess and overindulgence that first gripped me when I read this book. He states, "[t]o be listless, dull, bored, and lifeless is not only a miserable condition, it is an illness, a fact obvious to anyone who is intellectually alive. To respond to reality and to appreciate it are normal; not to respond is abnormal." Thus, to be a normal human is to have a capacity to appreciate objective beauty. The loss of such capacity is the result of something a person does. According to Dubay, "the chief cause of jadedness is a satiaton, a surfeit born of a hedonistic immersion in sensual gratifications, together with avarice and pride. A lifestyle of selfish egoism and continuing dissipation progressively deadens an excitement with reality born of innocence and solid virtue, self-denial, and genuine love." In other words, while a life of creature comforts is not intrinsically evil, it is a threat to intellectual life and an aid to boredom.
Dubay's The Evidential Power of Beauty is a great book--the kind filled with scores of paragraphs you
must pause and reflect on. It has long been a favorite of mine on the subject of aesthetics and truth. Another powerful and challenging read on the subject is David Bentley Hart's The Beauty of the Infinite: The Aesthetics of Christian Truth. Hart's book is a deep and virtually complete treatment of "theological aesthetics" that is a potent rejoinder to postmodernism. On a much lighter, but positively delightful, note, there is Robert Barron's Heaven in Stone and Glass: Experiencing the Spirituality of the Great Cathedrals. It is a meditation on the architecture and mystical space created by Gothic cathedrals. After reading this book, I saw the great cathedrals in an entirely different light. Their architectural forms and lines came alive with deeper meaning. Read this book and then visit a medieval Gothic cathedral for a sense of the connection between objective beauty and truth.
