All the several mental Qualities manifest in the voice, in tone, pitch or feeling. The Emotive Qualities give the affectionate voice; Self-Esteem gives the confident voice; Approbativeness gives the voice of affectation and conceit; Combativeness gives the "let me alone" tone; Destructiveness gives the "get out of my way" note; Cunning and Acquisitiveness give the tone of deceit and flattery; and so on, through the entire scale. In studying voices it will help you to ask "What Quality or Qualities produce this voice?" in each case. Study the voices of those whose characteristics you know, and then apply the experience to others whose characteristics are unknown. LAUGHS Laughter is full of the expression of character. One may often accurately determine the character of a person whose face is not seen or known. A hearty laugh is indicative of sympathy, companionship and general sociability, as well as a well developed sense of humor. A giggle is indicative of pettiness, trifling and general mental light-weight. The repressed laugh shows self-control and often caution and cunning, the tone denoting the difference. The vulgar "haw-haw" denotes a correspondingly gross nature. The peculiar shrill, rasping, parrot-like laugh of the courtesan is typical, and when ever heard should act as a note of warning. It is difficult to state in words the various qualities of the laugh, but each is distinctive and well expresses the Quality causing it. It may be said that each and every mental Quality has its corresponding note in the laugh, which note may be learned and recognized by a little practice and actual observation. THE HAND-SHAKE The manner of shaking hands is indicative of the characteristics of the individual. Handshakes may be divided into three general classes, viz, (1) the hearty handshake, which indicates good-feeling, earnestness, and interest; (2) the mechanical handshake, which denotes indifference, lack of feeling, and lack of interest; and (3) the selfish handshake, which denotes cunning, heartlessness, and desire and disposition to take advantage of the other party. There is a "something" in the handshake which is almost impossible to express in words, but which is recognized instinctively by those having Human Nature well developed. It is more of a "feeling" of certain Qualities manifested by the other person. A little thought and attention paid to this subject will tend to develop this recognition on the part of one deficient in it. One may, with a little practice, learn to distinguish between the honest and the dishonest; the moral and the immoral; the active and the passive; the energetic and the slothful; the grasp of good-fellowship, and that of superciliousness; the friendly and the antagonistic; the candid and the deceitful; and all the other various kinds of handshakes. Mental states manifest in outer form in handshakes as in many other physical actions and appearances.
