Writing a short book about a large thinker is its own discipline, and that is the discipline on show here. Adam Smith runs under four hours, which places it firmly in the tradition of the concise scholarly introduction. No padding, no biography by anecdote, just the argument made clear.
The contribution Christopher J. Berry makes here is compression, and the subject rewards it. Smith is invoked constantly and read rarely, which makes a compact, careful account genuinely useful rather than merely convenient.
Our shelves file the title under business and finance. That is not wrong, though the content sits closer to intellectual history than to practical advice. Come for the ideas rather than for a strategy.
