What is knowledge?
- What you know for certain. eg: 2+2=4, NOT "A baby knows how to suckle".
- A priori - Prior to experience
- A posteriori - Post experience
- Analytic - The truth is in the word, eg: A bachelor is an unmarried man is analytic because bachelor means unmarried man
- Synthetic - You need to check it to know it to be true, eg: my cat is white is synthetic because you need to check that my cat is white to know it.
A priori is always associated with analytic propositions, eg: A bachelor is an unmarried man is a priori analytic because you don't need to have experience of a bachelor to know that it is an unmarried man.
A posteriori is always associated with synthetic propositions, eg: My cat is white is a posteriori synthetic because the knowledge of my cat being white, or even the knowledge that I have a cat must come after (post) experience for you to know it to be true.
However, there has been an argument submitted by the rationalists that there is a priori synthetic. They argue that if you were locked in a cupboard with no experience of the world, and you (through reasoning) figured out that murdering another human being was wrong, that would be a priori synthetic.
