This is the context:
Once there is a limitation (from a self-referential paradox or in any other way), it is not hard to find other limitations by looking at reductions. One limitation can piggyback on another. In fact, a careful reading of chapter 6 and of section 9.3 will demonstrate that only one problem was shown to be computationally unsolvable: the Halting Problem. All the other problems were simply shown to be reductions of the Halting Problem. From a single limitation, one can go on to build an entire edifice of limitations. We wonder if perhaps every type of limitation somehow comes from some form of self-referential limitation or a reduction from such a limitation.

What is the meaning of "wonder if perhaps" in this context? I have trouble understanding this, because "if" and "perhaps" is in the sentence consecutively.
My take of it: "We are curious to know whether it is possible that the origins of every type of limitation are some form of self-referential limitation or a reduction from such a limitation."
