     The question corresponding to this proposition as answer is vague. But once the proposition this piece of mathematics has been done we are inclined to call it the proof that our question had to be answered is the positive. But, as one might say, there was much less in the question than there is now in the answer. – Compare this with: “Is 25 × 25 = 600?”
