xviii. The Fourfold Man of Earth
One must now make clear to oneself which one of the three bodies of man (the physical, the ether, and the astral body) is in its way most perfect. One can easily be tempted to consider the physical body as the lowest and therefore as the least perfect. However, in this, one would be in error. It is true that the astral body and the ether body will attain a high degree of perfection in the future, but at present the physical body is more perfect in its way than are they in theirs. Only because man has this physical body in common with the lowest natural realm on earth, the mineral realm, is it possible for the error we have mentioned to arise. For man has the ether body in common with the higher plant realm, and the astral body with the animal realm.
