paragraph_text: Value
  
  The value of knowledge is the worth it holds by expanding understanding and guiding action. Knowledge can have instrumental value by helping a person achieve their goals. For example, knowledge of a disease helps a doctor cure their patient, and knowledge of when a job interview starts helps a candidate arrive on time. The usefulness of a known fact depends on the circumstances. Knowledge of some facts may have little to no uses, like memorizing random phone numbers from an outdated phone book. Being able to assess the value of knowledge matters in choosing what information to acquire and transmit to others. It affects decisions like which subjects to teach at school and how to allocate funds to research projects.
  
  Of particular interest to epistemologists is the question of whether knowledge is more valuable than a mere opinion that is true. Knowledge and true opinion often have a similar usefulness since both are accurate representations of reality. For example, if a person wants to go to Larissa, a true opinion about how to get there may help them in the same way as knowledge does. Plato already considered this problem and suggested that knowledge is better because it is more stable. Another suggestion focuses on practical reasoning. It proposes that people put more trust in knowledge than in mere true beliefs when drawing conclusions and deciding what to do. A different response says that knowledge has intrinsic value, meaning that it is good in itself independent of its usefulness.
