Women of so-called "personality" often charm us because they approach 'nearer' than the average pretty woman does (however, the beautiful charmer may become the heroine of every man's unrealizable desire!)
Women with an attractive or winning personality are the women you feel irresistibly inclined to look at; the result being some sort of positive emotional effect that they 'stir up' within us.
The effect could be feelings of admiration, curiosity, or possibly, reverence. And some women have had so much "personality" and charm, that they've affected people like music, or like the pictures that speak to us.
In its subjective phase, personality is simply an extension of the mental/emotional self to relationships with other human beings. In its objective phase, it's the self which is observed by others.
