Let’s have a look at the first component:
This is a means of saying whether or not something is. In case something is, then that’s the answer we’re looking for. The piece of information following the 'if' is what we’ll be comparing with the piece of information following that piece of information.
Onto the following:
The world is always everything that is the case
This says that the world always is everything that is the case—meaning that all the time that ever will exist, the world is everything that is the case.
Here’s another component:
In this case, this describes that we’re comparing the first piece of information with the second due to the 'if'.
And the piece following the 'then':
Is it always the case?
This asks if the world always is the case.
We know that the world always is everything that is the case—pay attention to the 'always'. By asking “Is it always the case?” we have the answer—we just said the world always is the case, meaning that the second piece of information is true.
This yields me with my answer to you, which is yes.
