Three great scientific theories of the structure of the universe are the
molecular, the corpuscular and the atomic.  A fourth affirms, with
Haeckel, the condensation or precipitation of matter from ether -- whose
existence is proved by the condensation or precipitation ... A fifth
theory is held by idiots, but it is doubtful if they know any more about
the matter than the others.
