Industrial Progress and Human Economics — Inside the Classic

Habit as the Hidden Engine of Industry

Hartness devotes surprising attention to the mechanics of habit. He argues that even conversation 'must follow the line that has been carefully thought out,' and that spontaneous utterances are either subconscious reconstructions or 'a haphazard jumble.' This psychological observation is not a digression; it underpins his industrial philosophy. He illustrates with a concrete example: a manager who asks workers to 'think before acting' at the start of the day would make them all tardy. The implication is that efficiency relies on ingrained routines, not constant deliberation.

This view of habit as a productive force aligns with his broader critique of overthinking. He distinguishes between 'wholesome habit of thought and action' and the disruptive novelty of untested methods. The excerpts do not reveal whether Hartness extends this into a full theory of training or discipline, but the pattern is clear: human energy is best channeled through stable, well-designed habits rather than spontaneous innovation.

The Thin Stream: Capital and Inventory Discipline

A recurring motif in the excerpts is the image of stock flowing through a plant as a 'rapid but thin stream.' Hartness warns against tying up capital in raw materials, work-in-progress, or finished goods beyond what is necessary to ensure steady supply. He calls excessive inventory 'the outcome of carelessness' and a sign of 'slip-shod management.' The language is blunt: 'every dollar's worth of unnecessary stock on the shelves … represents idle money and faulty management.'

This emphasis on liquidity and turnover reflects Hartness's experience in machinery building, where demand is never steady. He notes that 'there is no such thing as a steady long-lived demand for any machine,' so a hand-to-mouth approach to stock may be prudent. The dividing line between sufficient and excessive inventory, he insists, must be drawn case by case. The excerpts do not specify how to calculate that line, but they establish a clear principle: capital should be put where it brings the best return, not left idle in storerooms.

Specialization vs. Adaptability: A Delicate Balance

Hartness acknowledges the benefits of specialization—highly skilled workers and efficient machines—but he also warns against its rigidity. He describes the 'tendency to divert the energies of the organization along new lines' as costly, noting that 'each new method … is dearly bought.' Yet he also advocates for 'adaptable equipment' that facilitates keeping down tied-up capital. The tension is explicit: specialization yields peak productivity, but it can also lock a plant into inflexible processes.

The excerpts do not resolve this tension. Hartness seems to advocate for a middle path: organizations should be specialized enough to achieve high efficiency but flexible enough to adjust to changing demand. He praises 'modern methods and machines which tend toward profitable use of capital,' suggesting that adaptability itself can be engineered. The reader is left to infer how Hartness would balance these competing priorities in practice.

Hartness's book is best read as a series of practical maxims grounded in a consistent worldview: human energy is the ultimate resource, and its efficient use requires disciplined habits, lean inventory, and a wary eye on novelty. The excerpts offer no grand theory of economics, but they do provide a clear, opinionated framework for industrial management. Readers should pay attention to the recurring contrasts—between habit and thought, stock and flow, specialization and adaptability—as they reveal the author's core concerns.

Reading Hartness, I kept thinking how he saw human energy as a quiet current, not a switch to be flipped. His thin stream of work-in-progress feels like my own half-finished afternoons. Later, I found a similar patience in The art of money getting — Themes and Context, where earning was less about grabbing than about steady, unhurried attention. Both books left me oddly grateful for the slowness I usually resist.
