"If a thing be really good, it can be shown to be such"

This quote by William Godwin suggests that if something is genuinely excellent, it will have the ability to withstand analysis and be shown to be so. This implies that if something is good, it will be able to hold up against any criticism or opposition and still be seen as excellent. This might be interpreted as a call to action for individuals to pursue excellence in their work and to ensure that their efforts are of the greatest quality. It could also be seen as a suggestion to be sincere and open about the quality of one's work, as it will have the ability to withstand any criticism. Ultimately, this quote motivates people to strive for quality and to be confident in the quality of their work.
