Physiognomy is not entirely a delusion. There is no "science" of Physiognomy, however, nor is it an exact art. The rules laid down by Adamantius were quite different from those of Aristotle, just as those of Baptist Porta and Robert Fludd were quite different from Levater's. Physiognomy is the art of knowing the humor, temperament or disposition of a person from observation of the lines of the face, and from the character of its members or features. While there is as yet no code of rules laid down by any author which constitutes a trustworthy guide, there in an apparent analogy between the mind and the countenance, which is discernible to keen observers. Probably every man and woman prides him or herself on the ability of translating expression, because we all imagine that we are good judges of human nature; yet, we have all erred in this regard, and often they were costly errors. Our instincts and intuitions, are perhaps the safest guides, after all, for there is but little reliance to be placed on the text books; and the common beliefs regarding the meaning of the features are anything but reliable. The best that can be done, for the present, is to assemble the predominating characteristics of the great men of history and compare these with their portraits. It is generally conceded that the greatest authority on Physiognomy is Levater; yet, in my copy of his principal work, which, by the way, is the voluminous 15th London edition, he says: "I understand but little of physiognomy, and have been, and continue daily to be, mistaken in my judgment." Since no greater physiognomist ever lived, it seems fair to assume that there is no "science" of physiognomy, and no infallible system with which we can read the character and capabilities of a person by means of the features. Whether such a science will yet be discovered or devised, remains to be seen. However, it is possible, and even probable, that the features all have meanings, even if we do not know those meanings, and that the code finally adopted by Levater is fairly correct. This being true, the best we can say for Physiognomy is that it _helps_ us to interpret character by showing us _tendencies_. That is, given a face the chin of which denotes firmness, and the mouth tenacity, we may be reasonably certain that the individual will have a strong tendency to do thus and so under certain conditions, provided those characteristics are not over-balanced and offset by other characteristics. That the tendency is not conclusive, is apparent: for the person may be born with a nose which, according to Physiognomy, denotes criminal propensities; yet, he may have overcome his immoral tendencies by means of education, religion or environment, while his nose remains unchanged. Again, he may have certain features which are said to denote generosity, for example, yet there may be various other features which denote love of power, acquisitiveness, vanity, etc.,
