This is an interesting, if brief look back at historical computing mechanisms. It is interesting for two reasons. First, that it focuses exclusively on tools for logical reasoning, and not on numerical tools like a slide rule or abacus. Second, it was written at the dawn of the electronic computing era, before even one-at-a-time transistors were used, and long before the earliest integrated circuit.
