All knowledge comes from somewhere. Even if we say it is innate (comes from within us) we still have to say how that knowledge appears. The Ways of Knowing are what they sound like, the methods through which knowledge becomes apparent to us. In the IB there are eight different ways of knowing: Language, Sense perception, Emotion, Reason, Imagination, Faith, Intuition and Memory. Although this might seem like a lot, the good news is that the for the IB you’re only really advised to study four of them in depth (although it’s worth knowing how each of them works).
