"[T]he paradox of Adams's personality; he genuinely loved and had deep compassion for humanity but never learned to deal with individual human beings. To his immediate family, he was a warm, generously loving man; to outsiders, he appeared cold, aloof, conceited. As a youth he was driven by ambition. He was determined to be a man of substance and, if circumstances afforded the opportunity, a great man. Throughout his life he wrestled with his passions. From his mother he inherited his pugnacity, drive, ready temper, and broad mood swings. He frequently fell to black despair, fits of depression that were triggered usually by the onset of some illness, public criticism, or lack of recognition of his achievements. Some historians believe that he may have been manic-depressive. Somewhat paranoid, too, he was quick to see in his unpopularity a plot by others to discredit him and steal credit for themselves. A proper Puritan, he was shocked by the open sexuality of eighteenth-century France. At a dinner party in Bordeaux in 1778, a Madame de Texel, addressing Adams with innocent frankness, wondered aloud how Adam and Eve ever learned how to have sex, for no one else was around to explain the facts of life to them. Adams was thoroughly embarrassed, having never before heard a woman discuss such matters. He blushed but quickly regained his composure to explain with mock seriousness."
