Knowledge and Belief

When can we claim to know something?

To know:

• Žinoti
• Wissen 

We can claim to know something if we learned about it in the past or experienced it or if someone told us about it. Also when we can explain something clearly with knowledge to someone who doesn't know anything about it. In History we use primary sources to justify something, in ,math  we show our work. 

People usually tend to think that if they understand something, they know it, which is usually not true. Knowledge is justified by true beliefs. We can only believe if we have evidence for it, in other words if we have a proper justification for it. 

Hoe do we know? (nature of knowledge) 

• Justified
• True
• Belief 
• If one has no beliefs 

Epistemology is a study of knowledge that include the nature of knowledge and the extent of human knowledge
