Falsehood always endeavors to copy the mien and attitude of truth. [ Dr. Johnson ]

Morality is simply the attitude we adopt toward people whom we personally dislike. [ Oscar Wilde, An Ideal Husband ]

Happiness is an interior matter, an attitude toward life, depending on the individual soul. [ George Hodges ]

Style seems to depend on three things:
1. a mental attitude and character,
2. a familiarity with the best authors,
3. dexterity in the use of words, acquired by constant practice.
So we must learn to speak by speaking, as we learn to walk by walking, or to dance by dancing. [ John Stuart Blackie, The Art Of Authorship, 1891 ]

Posture or Attitude? Each of these words has its appropriate place, and one should not be misapplied for the other. Posture is the mode of placing the body, and may be either natural or assumed. Attitude is always assumed, and is intended to display some grace of the body, or some affection or purpose of the mind. Postures, when natural, accommodate themselves to the convenience of the body; when assumed they may be either serious or ridiculous. [ Pure English, Hackett And Girvin, 1884 ]
