Quote by George Eliot
The dull mind, once arriving at an inference that flatters the desire, is rarely able to retain the impression that the notion from which the inference started was purely problematic.
Summary
This quote suggests that a dull mind, once it forms a conclusion or inference that aligns with its desires, is often unable to recognize or remember that the original idea or premise on which the inference was based was uncertain or doubtful. In other words, when a person's bias or inclination guides their thinking, they tend to overlook the lack of solid evidence or logic supporting their views, resulting in a flawed perception of reality.
