In conclusion, let us say that just as the above striking description of the master-scientist, Darwin, shows us that the particular emotion has its outer manifestations--the particular Inner State its Outer Form--so has the general _character_ of the person its outer manifestation, and Outer Form. And, just as to the eye of the experienced observer at a distance (even in the case of a photographic representation, particularly in the case of a moving picture) may recognize the Inner State from the Outer Form of the feeling or emotion, so may the experienced character reader interpret the whole character of the person from the Outer Form thereof. The two interpretations are based on exactly the same general principles. The inner thought and feeling manifest in the outer physical form. He who learns the alphabet of Outer Form may read page after page of the book of Human Nature. CHAPTER II THE INNER PHASE: CHARACTER Do you know what "character" is? The word itself, in its derivation and original usage, means: "a stamp, mark or sign, engraved or stamped." As time passed the term was applied to the personal peculiarities of individuals, and was defined as: "the personal qualities or attributes of a person; the distinguishing traits of a person." Later the term was extended to mean: "the part enacted by anyone in a play." In the common usage of the term we seek to convey an idea in which each and all of the above stated meanings are combined. A man's character is the result of _impressions_ made upon his own mind, or those of the race. It is also the sum of his personal qualities and attributes. It is also, in a sense, the part he plays in the great drama of life. Each man's character has its inner phase consisting of the accumulated impressions of the past which seek to manifest in the present. And, likewise, the character of each man manifests in an outer phase of form, mark, and stamp of _personality_. There are no two characters precisely alike. There is an infinite possibility of combination of the elements that go to make up character. This is accordance with what appears to be a universal law of nature, for there are no two blades of grass exactly alike, nor two grains of sand bearing an exact resemblance to each other. Nature seems to seek after and to manifest variety of form and quality. But, still, just as we may classify all things, animate and inanimate, into general classes and then into subordinate ones--each genus and each species having its particular characteristics, qualities and attributes, so we may, and do, classify human character into general classes and then into particular subdivisions into which each individual is found to fit. This fact makes it possible for us to study Human Nature as a science.
