"By action and reaction do we become strong or weak, according to the character of our thoughts and mental states. Fear is the deadly nightshade of the mind"
About this Quote
The punch comes from the moral edge of “according to the character of our thoughts and mental states.” Walker isn’t talking about fleeting moods. “Character” implies habit, discipline, a cultivated inner posture. In a late-19th-century context, this aligns with the era’s rising obsession with self-mastery and “muscular Christianity,” where physical training doubled as proof of virtue. The mind, in that worldview, is either a coach or a saboteur.
“Fear is the deadly nightshade of the mind” is vivid on purpose: nightshade isn’t just unpleasant, it’s poisonous and quietly fatal. Fear doesn’t always scream; it sedates, numbs, distorts perception. For an athlete, that means hesitation, tightness, and the domino effect of overthinking. Walker’s intent isn’t to deny risk or pain; it’s to argue that fear’s real damage is anticipatory. It convinces you to shrink before life (or the competition) even makes contact, and that retreat becomes its own training program.
