Natural science physics contains in itself synthetical judgments a priori, as principles. ... Space then is a necessary representation a priori, which serves for the foundation of all external intuitions.
Upon the solution of this problem, or upon sufficient proof of the impossibility of synthetical knowledge a priori, depends the existence or downfall of metaphysics.
This reminds me, Godmother, to ask you a serious question. You are as wise as wise can be (having been brought up by the fairies), and you can tell me this: Is it better to have had a good thing and lost it, or never to have had it?
You will profit by the failure, and will avoid it another time. I have done a similar thing myself, in construction, often. Every failure teaches a man something, if he will learn.
