In order that Form should come about, the forces of Saturn are required; for the formative process to take place in Wisdom-filled order, Jupiter’s forces are necessary. If form and order are to become manifest in the realm of earthly substance, both require the assistance of Mars. We can best form an idea of the part which Mars contributes to the coming into being of the world of Form in nature if we observe what takes place when we make use of speech as a medium for expressing our thoughts. In order to be able to shape a thought we have to participate in the formative force of Saturn. We depend upon Jupiter to bring about logical connexion between the single thoughts. To announce them to the world, we need the motive force of Mars, which enables us so to set external matter in motion that it becomes a carrier and relayer of our thoughts. (We here touch upon the field of the acoustic movements of the air which will occupy us more closely later on.)
