This abstract doctrine required to be elucidated and fixed. From a hypothesis to concentrate and reduce it to a reality was the great work of Bruno.
One is the perfect number; it is the primitive monad. As from the One proceeds the infinite series of numbers which again withdraw and are resolved into the One; so from Substance, which is one, proceed the myriads of worlds; from the worlds proceed myriads of living creatures; and from
the union of one with the diverse is generated the Universe. Hence the progression from ascent to descent, from spirit to that which we call matter; from the cause to the origin, and the process of metaphysics, which, from the finite world of sense rises to the intelligent, passing through the intermediate numbers of infinite substance to active being and cosmic reason.
From the absolute One, the sun of the sensible and intellectual world, millions of stars and suns are produced or developed. Each sun is the centre of as many worlds which are distributed in as many distinct series in an infinite number of concentric centres and systems. Each system is attracted, repelled, and moved by an infinite, internal passion, or attraction; each turns round its own centre, and moves in a spiral towards the centre of the whole, towards which centre they all tend with infinite passional ardour. For in this centre resides the sun of suns, the unity of unities, the temple, the altar of the universe, the sacred fire of Vesta, the vital principle of the universe.
That which occurs in the world of stars is reflected in the telluric world; everything has its centre, towards which it is attracted with fervour. All is thought, passion, and aspiration.
From this unity, which governs variety, from this movement of every world around its sun, of every sun around its centre sun—the sun of suns—which informs all with the rays of the spirit, with the light of thought—is generated that perfect harmony of colours, sounds, forms, which strike the sight and captivate and enthrall the intellect. That which in the heavens is harmony becomes, in the individual, morality, and in companies of human beings, law. That which is light in the spheres becomes intelligence and science in the world of the spirit and in humanity. We must study this harmony that rules the celestial worlds in order to deduce the laws which should govern civil bodies.
In the science of numbers dwells harmony, and therefore it behoves us to identify ourselves with this harmony, because from it is derived the harmonic law which draws men together into companies. Through the revolution of the worlds through space around their suns, from their order, their constancy and their measure, the mind comprehends the progress and conditions of men, and their duties towards each other. The Bible, the sacred book of man, is in the heavens; there does man find written the word of God.
Human souls are lights, distinct from the
universal soul, which is diffused over all and penetrates everything. A purifying process guides them from one existence to another, from one form to another, from one world to another. The life of man is more than an experience or trial; it is an effort, a struggle to reproduce and represent upon earth some of that goodness, beauty, and truth which are diffused over the universe and constitute its harmony.
