I consider the outline and position of the forehead to be the most important feature in physiognomy. We may divide foreheads into three principal classes—the retreating, the perpendicular, and the projecting, and each of these classes has a multitude of variations.
A few facts with respect to foreheads may now be given.
The higher the forehead, the more comprehension and the less activity.
The more compressed, short, and firm the forehead, the more compression and firmness, and the less volatility in the man.
The more curved and cornerless the outline, the more tender and flexible the character; and the more rectilinear, the more pertinacious and severe the character.
Perfect perpendicularity implies lack of understanding, but gently arched at top, capacity for cold, tranquil, profound thought.
A projecting forehead indicates imbecility, immaturity, weakness, stupidity.
A retreating forehead, in general, denotes superior imagination, wit, acuteness.
A forehead round and prominent above, straight below, and, on the whole, perpendicular, shows much understanding, life, sensibility, ardour.
