Eight Pillars of Prosperity is a practical book of ten chapters in which James Allen sets out to overturn a popular belief: that getting on in the world depends on dishonesty. He calls this view superficial and a sign of ignorance about moral causation. His own claim is that prosperity rests upon a moral foundation, and that the same law of cause and effect that governs the natural world also governs thought and deed. To sow trickery and expect lasting success, he says, is like sowing one seed and expecting a different crop.
Allen names eight principles that act as the causative factors in all genuine success: energy, economy, integrity, system, sympathy, sincerity, impartiality, and self-reliance. He pictures them as the pillars that support a temple of prosperity, with the roof of prosperity raised and made secure upon them. The boundary lines of a person's morality, he writes, mark the limits of that person's success, so that to know someone's moral state would be to gauge their ultimate rise or fall.
The first four pillars cover the working virtues. Energy is the power behind all achievement, the opposite of the laziness that leaves a person only half alive. Economy is not mainly about money but about conserving and rightly directing one's forces, as nature wastes nothing and turns everything to account. Integrity is the refusal to take without giving a just return, summed up in the principle that action and reaction are equal. System is the order that makes confusion impossible and lets large undertakings hold together.
The remaining four pillars Allen calls the central ones, belonging to a higher moral sphere. Sympathy is real fellow feeling rather than sentimental display, and he warns that cruelty at home unmasks any public show of pity. Sincerity is the trust that holds society and commerce together, since trade itself rests on the expectation that people will meet their obligations. Impartiality is the removal of prejudice and egotism, which otherwise fill life with imaginary enemies. Self-reliance, drawn partly from Emerson, is the manly confidence that neither shrinks in timidity nor swells into conceit.
The closing chapter explains why the book offered no tips on prices or contracts. Details cannot stand alone, Allen argues; they are endless and always changing, while principles are few and eternal, and a person who holds the principles can see through the details without anxiety. Prosperity is first a spirit and an attitude of mind that only afterward shows itself as plenty and happiness. Just as one becomes a genius by acquiring the soul of genius rather than by churning out poems, one becomes prosperous by acquiring the soul of virtue, after which the material results follow as effect to cause.
