David Hume's An Enquiry Concerning Human Understanding

In “An Enquiry Concerning Human Understanding” David Hume talks about two kind of human reasoning, relations of ideas and Matters of fact.

They are statements that are true simply in virtue of the concepts contained in them and not in virtue of the way the world is. They are true by definition and just have to know the meaning of the word to know if it true or false. Relations of ideas are also called

Therefore they are important, meaningful, or significant to human being. They are not true by definition.

Hume says, “The contrary of every matter of fact is still possible.” It means that matter of fact are something that is not false but there is a possibility that it can be also false like the bachelors non-messy apartment. According to Hume matter of facts are unjustified. We can have a priori knowledge only if it is a relations of ideas and matters of fact can be known only as a
