True wisdom is less presuming than folly. The wise man doubteth often, and changeth his mind; the fool is obstinate, and doubteth not; he knoweth all things but his own ignorance.

Summary

This quote suggests that true wisdom comes from being humble and open-minded. A wise person acknowledges their limitations and frequently questions their own beliefs, leading to growth and change. In contrast, a foolish person is stubborn and fails to doubt themselves. They may possess knowledge about various subjects, but they are unaware of their own ignorance. Ultimately, the quote emphasizes the importance of embracing one's own fallibility in order to cultivate genuine wisdom.
