“Man feeds upon air, the plant collecting the materials from the atmosphere and compounding them for his food. Even life itself, as we know it, is but a process of combustion, of which decomposition is the final conclusion; through this combustion all the constituents return back into air, a few ashes remaining to the earth from whence they came. But from these embers, slowly invisible flames, arise into regions where our science has no longer any value.”—Schleiden.
