>[!abstract] >Many philosophers define knowledge as justified true belief (JTB). This definition characterizes knowledge in relation to three essential features: [...] > >1. **Truth**. There is wide agreement that knowledge implies truth. In this regard, one cannot know things that are not true even if the corresponding belief is justified and rational. As an example, nobody can know that Winston Churchill won the 1996 US Presidential election, since this was not the result of the election. >2. **Belief**. Knowledge is usually understood as a form of belief: to know something implies that one believes it. This means that the agent accepts the proposition in question. >3. **Justification**. It is based on the idea that having a true belief is not sufficient for knowledge, that knowledge implies more than just being right about something. So beliefs based on dogmatic opinions, blind guesses, or erroneous reasoning do not constitute knowledge even if they are true. > >("Definitions of knowledge", 2025). This traditional view of knowledge was challenged in 1963 by the [[Gettier problem]]. ## References - Definitions of knowledge. (2025, January 1).
