fallibility

This term carries a philosophical and humble connotation, often used to describe the inherent limitations of human nature. It suggests a systemic vulnerability to error rather than a specific, one-time mistake. It is frequently employed in academic, legal, or theological discussions to argue against absolute certainty or infallibility.

As an uncountable noun, this word describes an abstract quality. It cannot be pluralized or counted with numbers; instead, it requires partitive constructions such as a sense of fallibility or the fallibility of a system to specify particular instances of the trait.
