The Transubstantiation of Grain

Have you noticed that seeds and grains possess identical appearances? Wheat planted as a seed is identical to the grain harvested later in the season. If so, why do we distinguish seed from grain when they are the same object? In the answer to the question lies what I believe is part of the mystery in the human story.

A seed planted produces a plant that reproduces itself as a seed. Grain, however, is a seed transformed by human intention when put in the service for other purposes. Further, I believe the cultivation of grain lies at the heart of civilization. Communal life as we know it, and the cultural elaboration that followed from it was, and remains, impossible without the cultivation of grain. Deep beneath the material aspects of grain cultivation lies a bit of cosmic mystery.

A grain appears identical to a seed but it isn’t. Grain’s destiny isn’t as a means of plant reproduction but as an agent of human transformation. It’s subtle but bear with me. Growing up on a farm, I participated in the differentiation of seeds and grains. Each spring we planted seeds to produce a crop in order to harvest the grains. Seeds were the means to the end, which was the harvest—the surplus production and sale of seeds beyond those needed for planting.

Planting corn or wheat each spring was our act of faith because we couldn’t control the weather, prevent infestations of wheat rust or cut worms, or changes in the price at market. Everyone depends on agriculture—grain—but few of us are directly connected to it. Nowadays we know grains indirectly and invisibly through their by-products: flour, grits, pasta and ethanol. Culturally, we think of ‘harvest’ and Thanksgiving as wrapping up a season in hoped for abundance and material security. It’s a warm, cozy idea but farmers are less sentimental. Harvest is do-or-die; the yield of grain per acre is a judgment on their management of resources and risks. The yield is the fulcrum for debt or surplus.

Grain underlies the larger mystery of settled human populations and the civilizations arising from them. Settled populations anchored themselves around and through the cultivation of wild grasses to harvest their seeds as food. Emmer and einkorn are the Middle Eastern ancestors of the modern wheat. Teosinte, a wild grass of Mesoamerica, became the mother of maize in all its forms, and is no longer a wild plant but depends on humans to reproduce.

Careful observation and selection over centuries produced plants able to produce greater yields of grain per acre, withstand droughts, winds, or blights. Humans chose grains with particular traits to maximize production on various soils and environments. Just as our ancestors domesticated or shaped the evolution of wild plants, in like manner the plants and their needs influenced and domesticated the shape and structure of human communities and cultures.

Dry grains, easily stored and transported, and densely nutritious, made it possible to amass surpluses to support larger communities and specialists, like potters, weavers, warriors, priests, and doctors. Cultivation accentuated the division of labor, the creation of classes, and defined gender roles. The particular needs of each grain—wheat, maize, sorghum, oats or barley—distinctly shaped the labor, lives, idioms, customs, and celebrations of the people who depended them. The relations between grains and humans is a symbiotic one. Neither modern civilization nor contemporary grains came into existence without the other.

Before the ‘Big Bang,’ our universe is believed to be compressed into something the size of a grain. Yet, within its cosmic hull lay everything that was, is, and will be. In a nano-second, this proto-universe hurled toward eternity the myriad potentialities that have and still interact, combine, and recombine as suns are born and die, galaxies form and disappear into black holes, civilizations rise and fall, and people are born, nourished and die.

Like the universe before the ‘Big Bang,’ a seed contains all the potentialities of the plant that grows from it and, by extension, the grain contains human intentions whose use will have primary, secondary and tertiary effects on human lives and civilizations. Grain is transformational in the human story. Although grain retains the outer form of a seed, the reason for its existence—its purpose—is altered, as if in a secular version of transubstantiation.
