Quote by G. C. (Georg Christoph) Lichtenb
To err is human also in so far as animals seldom or never err, or at least only the cleverest of them do so.
Summary
This quote suggests that making mistakes is a trait unique to humans, as animals rarely make errors, and if they do, it is only the most intelligent among them who make such mistakes. It highlights the fallibility of humans and implies that errors are a natural part of being human, contrasting it with the more predictable behavior of animals.
