👉 Non-certitude is a philosophical concept that refers to a state of complete lack of confidence or belief in something, especially when it comes to knowledge. It can be understood as a feeling of uncertainty about one's abilities and capabilities, or about certain events or situations, which makes them seem impossible or out of reach. In the context of noncertitude, a person may have a strong sense of certainty in their own beliefs and experiences, but feel very uncertain about the knowledge or reality that they possess.
