We must try harder to understand than to explain.

[...} many things must remain uncertain, and many a question insoluble, because what we know of nature is by no means sufficient, in all cases, to explain what has to be explained.

We're forever teetering on the brink of the unknowable, and trying to understand what can't be understood.

What we are trying to do is to understand this confusion and not cover it up with quotations.

We cannot understand. The best is perhaps what we understand least.

The reasons why I do things are difficult for me to understand and difficult for me to explain.

We can never be quite clear whether we are referring to the world as it is or to the world as we see it.

It's hard to explain and best thing to do is not be false.

As we acquire more knowledge, things do not become more comprehensible, but more mysterious.

Most of us are confused about what is real.

Our lot may be all-seeing and all-knowing, but that’s a long way removed from all-understanding.

Translation: although we don't know the meaning for everything now, we will soon

Confusion is a word we have invented for an order which is not understood.

We find things that do not fit into familiar frameworks hard to understand – such things seem meaningless.
