[K]nown as the Sign of the Craftsman or Critic, Virgo is Negative in polarity (as are Taurus, Cancer, Scorpio, Capricorn and Pisces). The general characteristics of Negative Signs lean toward introversion and prefer to draw upon personal resources rather than look for external stimuli. Such individuals are naturally more receptive, sensitive and nurturing than are the Zodiac Signs of Positive polarity (Aries, Gemini, Leo, Libra, Sagittarius and Aquarius). However, Negative Signs are ... likely to be much more cautious, retiring and standoffish than their Positive counterparts with a tendency to keep personal feelings under tight control. Taurus is the most introverted of the Negative Signs (with Virgo a close second).
