Back in, IIRC the 8th or 9th grade, back in the late 1950s, we were introduced to SI Hayakawa's textbook, Language in Thought and Action.
One of the concepts that has always served me well is "The Map is not the Territory". We like to place things in somewhat neat boxes and we call that stuff "knowledge", but the daffodil we know is not the actual item "daffodil". One is our map, the other is the territory.
Maps change. Not every place is yet mapped. And not one of the maps really is the territory. And even when we actually visit the territory what we bring away, what we call knowledge is still not the territory.
Knowledge is a critter creation. The knowledge we are most concerned with is simply a human creation. It is never the territory and exists only as long as there is someone that holds that particular map. And if the map gets burned that knowledge no longer exists. There may well be other "maps" that still exist but the one that burned no longer exists. And none of the maps will ever actually be the territory.
There is only natural laws and natural processes. The proof of that is that a machine, that has nothing but natural processes can count the onions in the field or determine when to water or determine the current temperature or read Macbeth or ...
There is no evidence of anything other than natural processes and natural things.
