Blavatsky & Atomism

Blavatsky writes in The Secret Doctrine (1888): "The atom is elastic, ergo, the atom is divisible, and must consist of particles, or of sub-atoms. And these sub-atoms? They are either non-elastic, and in such case they represent no dynamic importance, or, they are elastic also; and in that case, they, too, are subject to divisibility. And thus ad infinitum. But infinite divisibility of atoms resolves matter into simple centres of force, i.e., precludes the possibility of conceiving matter as an objective substance". Blavatsky's admirers think this is a mystical revelation, but it's merely prattle about atomism, an age-old philosophical debate.
