What is it to know what a thing is? Suppose I can identify a laurel tree by its smell, but not by the shape and colour of its leaves. Or the other way around. Do I know what a laurel tree is in each of these cases? Or suppose I am a scientist and can identify it by analysing its genome, but not by its smell nor by the shape and colour of the leaves... Suppose I know only or, on the contrary, do not know the uses people give to laurel leaves. How many properties of laurel must I know so that I can know what laurel is? I think I must know something, otherwise I wouldn't even know what the word"laurel" means. But what? It can't be just one small thing: I wouldn't say that I know what laurel is if I can identify it only by its smell.

Great question(s). I suggest that "the bottom line" philosophically in such matters involves whether your concept of a "laurel" enables you to identify the plant as distinct from other plants and things in general (including minerals, animals, computers,...). Another criterion that philosophers use involves identifying what features are necessary or sufficient for a thing to be what it is. Such an analysis will probably take shape in terms of differentiating a thing's essential characteristics from its accidental features. So, I assume that an essential feature of being laurel would be being a plant, but it would only be an accidental feature that the plant was used in ceremonies to make a kind of crown that was conferred on someone quite distinguished (a successful poet, say). Because things like laurels will have almost indefinitely many features (the way it tastes, the sound it makes or does not make, when harvested.....), we tend to prioritize what features are vital depending on the context. So, for a biologist the genome may be vital, but not vital for crowning a poet. I hope this is at least partly helpful!

Thanks for great question(s)!
