Knowing, believing and thinking clearly about word meanings

An essential part of good mental hygiene is having a clear understanding of the role language plays in leading us astray when reasoning about complex questions. The deceptively simple question 'What is knowledge?' attracts more than its fair share of linguistic confusions so today's Mind Patch will use it as a pretext to expose some common misunderstandings that people have about word meanings. And while the main point of this essay is to correct these misunderstandings, it will provide what I think is a fairly definitive answer to the knowledge question, and hopefully awaken the non-specialist reader to the scale of the rabbit hole that is language, and perhaps thereby cultivate in them a level of interest befitting these phenomena.

Philosophers may struggle to understand precisely what it means to know something, but the everyday intuitions of very small children are sophisticated enough to allow them to get away with using this word without anything remotely bad happening.

The perils of knowing too much.
To be fair, philosophers are also perfectly capable of using the word know appropriately at parties, but it's one thing to have an intuitive understanding of a word's meaning and quite another to arrive at an explicit account of what we mean by it.

Why none of us quite know what we're talking about

It would be hard to find an adult native speaker of English who was anything less than absolutely certain that they knew the meaning of the word mouse. It is, after all, a word that is perfectly at home in children's storybooks, and certainly nothing anyone would ever think of as a difficult technical term. About as many native speaking adults would also feel the same about the word rat, but not all of them could say with confidence how exactly a mouse differs from a rat, or apply their implicit understanding of what these words mean to distinguish say, a juvenile rat from an adult mouse. The average person knows a lot of things about these animals but not necessarily enough to tell them apart in every single case.

There's a whole genre of commonly confused animal terms in English with which we could make a similar observation: monkey vs. ape, alligator vs. crocodile, turtle vs. tortoise, rabbit vs. hare, frog vs. toad, crow vs. raven, and so on. Many of us struggle with at least some of these distinctions, or if not these particular examples, then others. In such cases, it's safe to say that our mental representations of the meanings of the words involved are not completely fleshed out despite whatever confidence we may have that we know what each of these words means individually. Of course, if our dinner depended on being able to tell various animal species apart, we'd probably do far better, but unless a distinction is relevant for something, we usually content ourselves with the thought that the details are known to somebody somewhere and that we could easily look them up if necessary.
