Tea bowls, the major expression of Zen art, seem at once both primitive and strikingly modern. To begin to understand this contradiction we must go back to our own nineteenth century in the West, when tastes ran to decoration for its own sake and the rule of perfect, symmetrical, polished form was the aesthetic ideal. Into this smug, serene sea of aesthetic sureties, which in some ways reached back to the ancient Greeks, the English critic John Ruskin threw a boulder when he wrote:
_Never demand an exact finish for its own sake, but only for some practical or noble end. . . . [t]he demand for perfection is always a sign of a misunderstanding of the ends of art. . . . Imperfection is in some sort essential to all we know of life. It is the sign of life in a mortal body. . . . To banish imperfection is to destroy expression, to check exertion, to paralyze vitality. All things are literally better, lovelier, and more beloved for the imperfections which have been divinely appointed.1
Ruskin was rediscovering a large piece of Zen aesthetic theory while laying the groundwork for many of our modern ideals of beauty.
To see the similarity, let us examine for a moment a few of the finer points of Zen aesthetic theory as exemplified in the classic tea bowls. In form the bowls are frequently asymmetrical and imperfect; the glaze seems to be a species of moss still in the process of spreading over portions of the sides it somehow never managed to reach, and it is uneven, marred by cracks, lumps, scratches, and foreign contaminants. If imperfection is the goal, these bowls extend well beyond Ruskin's original standards. But not only are they imperfect, they also seem old and weathered, with the natural patina of a dried-up riverbed. They show absolutely no evidence that any conscious attempt was made to create a work of art; they appear to be completely functional.
It is all a deception. Master potters spend literally decades perfecting the Zen art of the controlled haphazard. One of the first principles they honor is _wabi_, which deplores nonfunctional decorative objects, polished surfaces, artificiality in shape or color, and anything unnatural to the materials used. Works of art without _wabi_ may have superficial external beauty, but they forfeit inner warmth. Bowls out of shape, with cracks, blobs, and ashes in the glaze, invite us to partake of the process of creation through their asymmetry and imperfection. They also lead us past the surface by virtue of its being deliberately marred.
