There are three universal principles, and they can be represented in a myriad of ways. Today, scientists would call them Positive, Negative, or Neutral forces, but they extend beyond the physical into the mental realms.

Which is why we Hermeticists refer not to a term like "Neutron" for a one neutral force, because it is a super-class of things that are neutral. When the alchemists of old use the term "Vulgar Sulphur" - they mean the actual physical chemical - when they use the term "Sublimed/Philosophic Sulphur", they mean the idea of the ACTIVE Principle or Force in the universe.
