Understanding

Understanding is a psychological state in relation to an object or person whereby one is able to think about it and use concepts to be able to deal adequately with that object.

Is understanding definable?

It is difficult to define understanding, however. If we use the term 'concept', as above, the question then arises as to what is a concept? Is it an abstract thing? a brain pattern? A rule? Whatever definition is proposed, we can still ask how it is that we understand the thing that features in the definition: we can never satisfactorily define 'concept', still less use it to explain understanding.

We can instead use an operational or behavioural definition: we can say that somebody who reacts appropriately to X, understands X. For example, I understand Swahili if I correctly obey commands given in that language.

However, this may not be an adequate definition. A computer can easily be programmed to react appropriately to simple commands. For most people, it would stretch the notion of understanding to still claim that under an operational definition, the computer understands the language.
