The first type of knowledge is personal knowledge, or knowledge by acquaintance.

Knowledge in this sense is to do with being familiar with something: in order to know Amy, one must have met her; in order to know fear, one must have experienced it. In each of these cases, the word “know” is being use to refer to knowledge by acquaintance.

Personal knowledge does, arguably, involve possessing at least some propositional knowledge. If I have met Amy, but can’t remember a single thing about her, then I probably wouldn’t claim to know her. In fact, knowing a person (in the sense required for knowledge by acquaintance) does seem to involve knowing a significant number of propositions about them.

What is important is that personal knowledge involves more than knowledge of propositions. No matter how much you tell me about Amy, no matter how many facts about her I learn, if I haven’t met her then I can’t be said to know her in the sense required for personal knowledge.

Personal knowledge thus seems to involve coming to know a certain number of propositions in a particular way.
