Occam's razor in atomism?

"Occam's Razor" is a statement of technique offered by Father Willaim de Ockham (Occam) of England-- who was later chided by Spinoza for mixing scientific methods with theology. The correct statement Okham made was: Pluralitas non est ponenda sine necesitate. "Do not complicate without reason." It is NOT defined as "the simplest explanation is usually the correct one", but properly defined as saying that when considering any question or issue, all INESSENTIALS must be stripped away; then clarity is ensured. However, Okham was looking for a technique which could be used to define God, and this is why Spinoza chastised him. Otherwise Spinoza had great admiration for Okham.
