Activists chant, “Water is life.” Introductory chemistry teachers instruct, “Water is the universal solvent.” Because of water’s exceptional ability to dismember all sorts of materials – carbon-based molecules, metals, salts – as well as its ability to absorb all sorts of gases – paleontologists tend to assume that life on Earth began in a body of water.
Dear Friends: Almost anything can serve as a weapon, even life-giving water. All living creatures on earth have evolved (are evolving) fortifications against attack. Cellular life is fortified by membranes, and human societies are fortified by lines in the sand. Nutrients and attractive ideas gain access through those fortifications. Poisons and slander are rebuffed.
