What is meant by understanding anyhow?

[...]

For example, do we ‘understand’ fields in the same sense that we believe them to be physically real, or do we ‘understand’ them as abstractions? (Are abstractions real?) 

[...]

Do we ever ‘understand’ or do we, in reality, use language to create ourselves an illusion of understanding? All we can really be confident about is that, when we do mathematics, we get answers that (a) agree with observations and (b) lead to verifiable predictions.

[...]

it is salutary to reflect on the extent to which enculturation – indoctrination – is what education is about.
