What you’ll learn

From impression to judgmentTrace how common sense turns impressions into a tested judgment.The garden metaphor and the book’s account of illusion lead to a definition rooted in truth, directness, and deliberate reasoning.
Consequences and contextUse foresight and proportion to fit a decision to its consequences and circumstances.The banquet and clothing examples show how judgment makes the future and the situation visible.
Practicing durable judgmentTreat common sense as a cultivated practice that can support durable ambition.Attention, comparison, and perspective-taking strengthen judgment, while the brass image separates durability from excitement.
