All partial principles therefore are established in that principle which ranks as a whole, and are comprehended in it, not with interval and multitude, but as parts in the whole, as multitude in the one, and number in the monad.

For it is necessary that the idiom of principle, after the same manner as other things, should not begin from multitude, but should be collected into one monad as a summit, and which is the principle of principles.

As the monad and the centre of a circle are images from their simplicity of this greatest of principles, so likewise do they perspicuously shadow forth to us its causal comprehension of all things.

For all number may be considered as subsisting occultly in the monad, and the circle in the centre; this occult being the same in each with causal subsistence.

But from the Timaeus you may obtain the theory about intelligibles, a divine narration about the demiurgic monad, and the most full truth about the mundane gods.

Hence this first one is truly the unity of unities, the monad of monads, the principle of principles, the God of gods, one and all things, and yet one prior to all.

All organisms are composed of minute elements, called minima or monads; each monad is a mirror of the All; each at once corporeal and soul-like, matter and form, each eternal; their combinations alone being in constant change.

Their non-spatial or punctual character implies the impossibility of all external influence, the monad develops its states from its own inner nature, has need of no other thing, is sufficient unto itself, and therefore deserves the Aristotelian name, entelechy.

These obscure states of unconscious representation, which are present in the mind of man along with states of clear consciousness, make up, in the lowest grade of existence, the whole life of the monad.

What now is the manifold, which is expressed, perceived, or represented, in the unit, the monad?

Every monad is thus a mirror of the universe, but a living mirror (miror vivant de l'univers), which generates the images of things by its own activity or develops them from inner germs, without experiencing influences from without.

The monad has no windows through which anything could pass in or out, but in its action is dependent only on God and on itself.

The objects of representation are merely representing subjects; the monad A represents the monads from B to Z, while these in turn do nothing more than represent one another.

The clearer the representations of a monad the more active it is.

This matter, as a constituent of the monad, does not mean corporeality, but only the ground for the arrest of its activity.

The monad develops its representations out of itself, from the germs which form its nature.

The unity, as well as the difference, could not be greater than it is; every possible degree of distinctness of representation is present in each single monad, and yet there is a single harmonic accord in which the unnumbered tones unite.

It was, therefore, not the perfection of the single monad, but the perfection of the system of which it forms a necessary part, that was decisive as to its admission into existence.

The dominant monad is distinguished from those which surround it as its body by the greater distinctness of its ideas.

The supremacy of the soul-monad consists in this one superior quality, that it is more active and more perfect, and clearly reflects that which the body-monads represent but obscurely.

Body exists only as a confused idea in the feeling subject; since, nevertheless, a reality without the mind, namely, an immaterial monad-aggregate, corresponds to it, the phenomenon of body is a well-founded one (phenomenon bene fundatum).

The monad has no windows.

The connection and the order of the world demands a material element in the monad, but happiness without alloy can never be the lot of a spirit joined to a body.

I do not know whether there be nothingness, or existence without space and time; perhaps some midplanetary wind carries the spiritual monad from star to star to implant it in an ever-renewing existence.
