2) But biology has a funny way of confounding expectations. Rather than disappear, the evidence for innate sexual differences only began to mount. In medicine, researchers documented that heart disease strikes men at a younger age than it does women and that women have a more moderate physiological response to stress. Researchers found subtle neurological differences between the sexes both in the brain’s structure and in its functioning. In addition, another generation of parents discovered that, despite their best efforts to give baseballs to their daughters and sewing kits to their sons, girls still flocked to dollhouses while boys clambered into tree forts. Perhaps nature is more important than nurture after all. —Christine Gorman, “Sizing up the Sexes”

1) So, Grant and Lee were in complete contrast, representing two diametrically opposed elements in American life. Grant was the modern man emerging; beyond him, ready to come on the stage, was the great age of steel and machinery, of crowded cities and a restless, burgeoning vitality. Lee might have ridden down from the old age of chivalry, lance in hand, silken banner fluttering over his head. Each man was the perfect champion of his cause, drawing both his strengths and his weaknesses from the people he led. —Bruce Catton, “Grant and Lee: A Study in Contrasts”
