Professor O. S. Fowler says that this Quality gives "the desire to know the why and wherefore of things, and to investigate their laws; ability to reason from causes down to effects, and from effects up to causes; the therefore and wherefore; ability to adapt ways and means to ends, to plan, contrive, invent, create resources, apply power advantageously, make heads save hands, kill two birds with one stone, predict the results of given measures, etc."
This Quality manifests outer form in the sides of the upper part of the forehead, one either side of Analysis and over Locality (see group figure). When large it gives to the forehead a "high, bold, square" form. With large Perceptives this Quality does not present so prominent an appearance and so marked a comparison, but with the Perceptives small it gives to the brow an "overhanging" appearance. With Analysis equally, or nearly as strong, the fullness of course extends well across the forehead; but with Analysis much smaller, Logic presents a bulging on each side of the forehead; while with Analysis large and Logic small, the latter gives the appearance of two depressions on each side of the forehead.
Spurzheim well says of the combination of Analysis and Logic (which he terms "Comparison" and "Causality," respectively): "Causality and Comparison combined constitute Reason. Without Causality (Logic) there can be no argumentative reasoning; without Comparison (Analysis), no comprehensive views, and no nice distinctions. Observation teaches objects, and Eventuality facts, while Comparison (Analysis) points out their identity, analogy, difference or harmony, whereas Causality (Logic) seeks their causes, and all together discern general principles and laws; draw conclusions, inductions and creations, and constitute a truly philosophical understanding."
