Combe says of this Propensity: "After more than thirty years experience of the world in actual life, and in various countries, I cannot remember an instance in which I have been permanently treated unjustly by one in whom this organ and intellect were large. Momentary injustice, through irritation or misrepresentation, may have been done; but after correct information and time to become cool, I have found such persons ever disposed to act on the dictates of Conscience; as well satisfied with justice.... It leads to punctuality in keeping appointments so as not to waste their time; to the ready payment of debts; will not send collectors away unsatisfied except from inability to pay; are reserved in making promises, but punctual in keeping them; and when favorably combined, are consistent in conduct.... Its predominance makes a strict disciplinarian and a rigid but just master; invests all actions with a sense of duty; thereby sometimes rendering estimable persons disagreeable." In normal manifestation this Quality renders its possessor a most worthy and estimable individual; but when abnormally developed and not balanced by judgment and the reasoning faculties, it produces persecutors and religious and ethical tyrants, adhering to the letter of the law rather than to its spirit. Conscience is generally esteemed, but careful observers deplore the "ingrown conscience" and "blue-law spirit" of those of large Conscientiousness, large Destructiveness, and small Sympathy. Many so-called "reformers" belong to this last class. This Quality manifests outer form on the side of the top part of the head, just below and on either side of Firmness. It lies between Firmness and Cautiousness, with Optimism just in front of it and Approbativeness just back of it (see group figure). CHAPTER XVI FACES Next to the shape of the head, the facial expression furnishes us with the most marked indication of the outer form accompanying the inner mental state. In fact, many authorities hold that the facial expression affords the most easily read and most comprehensive index of character, and that, therefore, Physiognomy possesses many points of superiority over Phrenology. The truth seems to be that Physiognomy and Phrenology are twin-sciences, and that the true student of Human Nature should acquaint himself thoroughly with both.
