_Reader._ How do you show that we have neither any knowledge nor any conception of the absolute? or that our understanding is limited by time and space? or that, from being accustomed to find a cause for every effect, we have _falsely_ concluded that there exists a primary cause of all things? or that its existence is contradicted by scientific experience? Of course you cannot expect that a rational man will swallow such paradoxes on your puny authority. _Büchner._ We know neither absolute truth, nor absolute good, nor absolute beauty. This I have shown by proving that all our notions of truth, of good, and of beauty are the fruit of experience, observation, and comparison, and that such notions vary according to the character of the nations in which they are to be found. It is only after this demonstration that I concluded “that we can have neither any knowledge nor any conception of the absolute.” _Reader._ Yes; this is the only point which you have tried to establish, and you have failed, as I am ready to show. But that our understanding is limited by time and space you merely assert. That we falsely conclude that there is a primary cause you boldly assume. That God’s existence is contradicted by scientific experience you impudently affirm, well knowing that it is a lie. And now, with regard to the knowledge of the absolute, you are much mistaken if you believe that we know no absolute truth, no absolute good, and no absolute beauty. We know absolute being; and therefore we know absolute truth, absolute good, and absolute beauty. _Büchner._ We know of no absolute being, sir.
