"Her virtue was that she said what she thought, her vice that what she thought didn't amount to much"

This quote by Peter Ustinov speaks with the concept that one's virtue can also be their vice. In this case, the female's virtue is that she speaks her mind and is sincere with her thoughts. Nevertheless, her vice is that her ideas don't have much substance or worth. This could be analyzed as a commentary on the concept that one's viewpoint is only as valuable as the knowledge and experience that they bring to the table. It might likewise be seen as a reminder that it is necessary to think prior to speaking, as one's words can have a lasting effect. Eventually, this quote functions as a suggestion that it is important to be conscious of the words we choose to use and the thoughts we choose to share.
