A quote
She thought that to indulge her passion and take vengeance on her husband was more profitable than to spare her children. It was so; but she was deceived. Show her plainly that she is deceived, and she will not do it; but so long as you do not show it, what can she follow except that which appears to herself (her opinion)? Nothing else. Why then are you angry with the unhappy woman that she has been bewildered about the most important things, and is become a viper instead of a human creature? And why not, if it is possible, rather pity, as we pity the blind and the lame, so those who are blinded and maimed in the faculties which are supreme?
