For remember that in general we don't use language according to strict rules — it hasn't been taught us by means of strict rules, either. - Ludwig Wittgenstein

If a lion could speak, we could not understand him.

Either a thing has properties that nothing else has, in which case we can immediately use a description to distinguish it from the others and refer to it; or, on the other hand, there are several things that have the whole set of their properties in common, in which case it is quite impossible to indicate one of them. For if there is nothing to distinguish a thing, I cannot distinguish it, since otherwise it would be distinguished after all.

Another alternative would have been to give you what’s called a popular-scientific lecture, that is a lecture intended to make you believe that you understand a thing which actually you don’t understand, and to gratify what I believe to be on of the lowest desires of modern people, namely the superficial curiosity about the latest discoveries of science.
