There is a positive force, meaning constructive, and a negative force, meaning negative and destructive. They create and complement the entire reality in general and particular through their harsh and perpetual war with one another. As we have said above, the negative force appears at the end of every political phase, elevating it to a better state, and thus the phases follow one another until they reach their ultimate perfection.

Let us take planet Earth as an example: first, it was but a ball of fog-like gas. Through the gravity inside it, it concentrated the atoms in it, over a period of time, into a closer circle. As a result, the ball of gas was turned into a liquid ball of fire.

Over eons of terrible wars between the two forces in Earth, the positive and the negative, the chilling force in it was finally triumphant over the force of liquid fire, and cooled a thin crust around the Earth and hardened there.

However, the planet had not yet grown still from the war between the forces, and after some time the liquid force of fire overpowered and erupted in a great noise from the bowels of the Earth, rising and shattering the cold hard crust to pieces, turning the planet into a liquid ball of fire once again. Then an era of new wars began until the cool force overpowered the force of fire once more, and a second crust was chilled around the ball, harder, thicker and more durable against the outbreak of the fluids from amidst the ball.

This time it lasted longer, but at last, the liquid forces overpowered once again and erupted from the bowels of the Earth, breaking the crust in pieces. Once more, everything was ruined and became a liquid ball.

Thus, the eons interchanged, and every time the cooling force was victorious, the crust it made was thicker. Finally, the positive forces overpowered the negative forces and they came into complete harmony: the liquids took their place in the abdomen of the Earth, and the cold crust became thick enough around them to enable the creation of organic life as it is today.

All organic bodies develop by the same order. From the moment they are planted to the end of the ripening, they undergo several hundred situations due to the two forces, the positive and the negative, and their war against each other, as described regarding the Earth. These wars yield the ripening of the fruit.

Every living thing begins also with a tiny drop of fluid, and through gradual development over several hundred phases by the power of the tug-of-war, finally reaches…

…a great ox fitting for every labor, or a grown person fit for his tasks. However, there should be yet another difference between the ox and the human: today, the ox has already reached its ultimate phase of development. For us, however, the material force is yet insufficient to bring us to completion because of the contemplative power in us, which is thousands of time more valuable than the material force in us. Thus, for humans there is a new order of gradual development, unlike any other animal; it is the gradual development of human thought.

In addition, being a social creature, the individual development is not enough. Rather, one’s ultimate perfection depends on the development of all the members of society.
