Having unconnected knowledge of this and that is not at all the same — it is a junkyard. Having mere words is not the same — it is faking knowledge.
We need to form conclusions ourselves from real knowledge: what we experience, what we conceptualize, what we really learn from others.
We can get a start from some maps, but knowledge happens only when we take the trip ourselves. We know nothing until we journeyed into the wilderness and returned — for each conclusion we reach.
