 On the other hand, a real essence is an essence because it makes the object to be what it is. It is real in that it does not include human choice for it to be what it is, rather, it is precisely as nature made it. In the case of a piece of gold, the real essence for the corpuscularian is that collection of particles that make up that particular piece of gold and give it its qualities of color, weight, electrical conductivity, malleability, etc.
